5.
They left the theme park with a hint of regret lingering in their hearts, but a promise passed between them with quiet certainty: We’ll come back again.
Yoo Ji-han drove calmly down the evening-lit roads. The city lights were just beginning to glow in the distance as the night sky dawned over the atmospheric layers. Chae Yoo-jeong sat beside him, glancing sideways with a sparkle in his eyes. The excitement of their 1st year anniversary hasn't faded away although the day is almost over soon.
“I wanted to say this earlier, but I was too surprised… I didn’t know you could drive.”
Chae Yoo-jeong spoke as he gazed at Yoo Ji-han with sparkles in his eyes. Yoo Ji-han chuckled lightly, eyes fixed on the road.
“Well, I used to drive trucks, so I had to get a license. It just kind of stuck with me. Though… It's been a while. I hope I don’t scratch your car by accident.”
He laughed nervously, then coughed, blushing faintly.
“You drive perfectly, Hyung!”
Chae Yoo-jeong said with a big smile.
Yoo Ji-han smiled, shaking his head in amusement.
“You always say I do everything perfectly, Yoo-jeong-ah.”
“Because you do everything perfectly, Hyung!”
Yoo Ji-han glanced at him for a moment, catching the playful pout forming on his lips. His expression softened. Without taking his eyes off the road, he gently reached over, took Chae Yoo-jeong’s hand, and pressed a soft kiss to the back of it.
Chae Yoo-jeong flinched at the sudden gesture, his cheeks flushing a deep red—but he didn’t pull away.
“And you.”
Yoo Ji-han murmured with a faint smile.
“…are perfect too.”
‘…Especially for me.’
They drove to a traditional Korean restaurant, where Yoo Ji-han had reserved a private room in advance. The warm lighting and soft clink of dishes in the background made the room feel comfortably intimate.
“Well……”
Yoo Ji-han said as he sat down, pulling out his phone and placing it gently on the table.
“While we’re waiting… want to look at my photo album?”
Chae Yoo-jeong’s eyes lit up instantly, a smile blooming across his face.
“Really?”
Yoo Ji-han nodded and handed over the phone, already opened to his older photo albums. He had thought about taking Chae Yoo-jeong to visit their elementary school—but he knew that it might bring back painful memories.
Chae Yoo-jeong scrolled through the photos, as his fingers were brushing the screen like it was something precious. His eyes sparkled with nostalgia, and gradually, tears began to form. Yoo Ji-han noticed the way his expression trembled, and without saying a word, reached out and rested a hand gently over Chae Yoo-jeong’s.
When Chae Yoo-jeong looked up, Yoo Ji-han met his gaze with a warm, reassuring smile.
Chae Yoo-jeong smiled back, the tears turning into a soft laugh as he began pointing at pictures and talking excitedly.
Dinner arrived soon after, and they set the phone aside to enjoy the delicious spread. Between bites, they chatted about college life. The room filled with easy laughter and the occasional clinking of chopsticks.
When they finished eating half of the food, Chae Yoo-jeong eagerly picked up the phone again.
“I’m going to print one of these and keep it in my wallet.”
Chae Yoo-jeong said with a mischievous smile, pointing at a particular photo.
“Is that okay, Hyung?”
The picture he showed was of Yoo Ji-han during high school—leaning casually against the open window of a classroom, hair tousled perfectly by the breeze, sunlight brushing his features. His smile in the photo was easy and warm, almost cinematic.
Chae Yoo-jeong’s eyes sparkled with admiration, as if there was a heart practically visible in his eyes.
Yoo Ji-han raised an eyebrow, feigning jealousy.
“Are you falling for the me in the photo more than the me sitting right here?”
Yoo Ji-han was slightly pouting with his hands crossed, with his eyes in another direction away from it.
“Why would you need a photo when you already have me by yourself?”
Chae Yoo-jeong laughed, holding the phone closer to his chest.
“Can’t I have both?”
Rolling her eyes backwards, Yoo Ji-han chuckled and leaned back. It felt like his heart was quietly full.
“You can have all of me, Yoo-jung-ah. Then and now.”
“Then……. What about this picture we took together today? It came out great.”
He turned the phone screen toward Yoo Ji-han.
A picture of them kissing, while Yoo Ji-han is holding an ice cream mid-bite, his eyes closed, cheeks slightly pink, and Chae Yoo-jeong smiling into the kiss. Yoo Ji-han’s eyes widened.
‘A picture of us kissing……. while I was holding an ice cream!!’
Yoo Ji-han snatched his phone back from Chae Yoo-jeong’s side, staring at the photo intently.
“When did you take a picture like this…….?”
‘Damn it. He looks too cute to be real…… I am printing this out and putting it in my wallet. Without question!’
While he was distracted, Chae Yoo-jeong picked up a piece of food with his chopsticks and popped it into Yoo Ji-han’s slightly open mouth.
“This is so good.”
Yoo Ji-han murmured with a soft smile on his face. Chae Yoo-jeong stopped for a second, watching his dear hyung with fond eyes before chuckling lightly.
“Yes, Hyung….very good.”
He gently set the phone down on the table and began eating as well. Outside the window, the sky was already darkening, soft hues of dusk melting into deeper shades of night.
They didn’t order any drinks. Yoo Ji-han knew that Chae Yoo-jeong was a lightweight, and neither of them wanted to blur the edges of such a special evening. This night wasn’t meant for hazy memories, it was meant to be remembered clearly, every smile, every word, every touch, every feeling.
After they finished eating, Yoo Ji-han stood up from the table. Chae Yoo-jeong followed a moment later, rising quietly. Yoo Ji-han looked at him briefly, then reached out and gently took his hand, leading him toward the door without a word.
Chae Yoo-jeong blinked in surprise because they didn’t pay the bill yet but followed in silence. He looked back and saw the staff, who bowed slightly with understanding and warm smiles, as the door opened.
‘Do they know Hyung? I will ask Hyung later……’
They stepped out into the night, the cool air brushing against their skin as they left the restaurant. The sound of the door shutting behind them seemed to seal the moment like the final page of a chapter.
As they walked under the soft glow of a lamplight, Chae Yoo-jeong suddenly tugged on Yoo Ji-han’s hand, pulling him into a quiet, steady hug. The dim light cast gentle shadows on their figures as Yoo Ji-han's eyes widened, his entire body freezing just for a second, before slowly relaxing, his arms wrapping around Chae Yoo-jeong in return. He closed his eyes, blinking slowly. He slipped his tongue into his mouth, while exchanging the small warmth across their whole bodies. After being swallowed by the breath-taking kiss, they drifted from each other and dreamy stared into each other’s eyes.
‘I hope we’ll be together for many years from now……’
They stood like that for a moment, as the world around them felt quiet. Then, they began walking home hand in hand, as if they were the only two people in the world.
***
Yoo Ji-han opened the door, stepping inside with Chae Yoo-jeong right beside him, both carrying bags filled with things they had bought or won. After quietly closing the door behind them, Yoo Ji-han glanced instinctively at the clock, then flicked on the lights and shrugged off his jacket.
The apartment was just as they had left it—still, calm, and warmly familiar.
Chae Yoo-jeong headed into the kitchen to put their things away while Yoo Ji-han dropped onto the couch, letting the soft cushions cradle his body. He leaned back, with his gaze drifting to the ceiling, and thoughts of the day playing behind his closed eyes.
‘Ugh……. So tired.’
A quiet smile spread across his face when he felt something warm wrapped gently around his neck.
“Hyung, are you tired?”
Chae Yoo-jeong’s soft voice came from the left. Yoo Ji-han didn’t open his eyes—he simply shook his head with a small, contented smile. Leaning towards him closer, Chae Yoo-jeong’s lips brushing lightly against Yoo Ji-han’s ear. A playful nip made Yoo Ji-han flinch, eyes snapping open in surprise.
“Do you want to go take a bath first or should I…?”
Chae Yoo-jeong whispered. His voice seemed like he was teasing him but somehow low and smooth suitable to the night surroundings and vibes.
Yoo Ji-han’s face flushed instantly, with his burning red ears. He tried to sit up straight, flustered, however Chae Yoo-jeong moved quickly, now facing him, eyes glinting with mischief. In one fluid motion, he tugged Yoo Ji-han’s legs around his waist, catching him off guard. Yoo Ji-han nearly lost balance but instinctively held on, steadying them both.
“You really hold me up really well……?”
Chae Yoo-jeong murmured with a grin. His hands rested lightly on Yoo Ji-han’s waist for support.
‘Will he even be able to carry me like this? Although he’s tired…….’
While he thought that, Yoo Ji-han blinked at him, stunned and breathless, somewhere between embarrassment and laughter. He lightly flicked on Chae Yoo-jeong’s forehead.
“You’re going to give me a heart attack, you know that?”
Chae Yoo-jung chuckled, leaning his forehead gently against Yoo Ji-han’s.
“Then I’ll take responsibility.”
Yoo Ji-han rolled his eyes, though the smile tugging at the corner of his lips betrayed his amusement. He asked, voice thick with sarcasm.
“What responsibility would you take?... Put me down, Chae Yoo-jeong.”
Chae Yoo-jeong laughed softly but obeyed, carefully setting Yoo Ji-han back down on the sofa. Yoo Ji-han let out a long sigh, shaking his head as he stretched out with a groan.
“I need a moment to rest……”
He said, tilting his head back against the cushions.
“So go and shower.”
Chae Yoo-jeong replied with a playful tone.
“Okay……. Then I’ll shower quickly, so make sure you do too.”
As he turned to leave, Yoo Ji-han reached out and patted him affectionately on the head. His fingers ruffled through the soft, golden strands of Chae Yoo-jeong’s hair.
With that, he disappeared into the bathroom beside the living room. The soft click of the door closing echoed through the quiet apartment.
Yoo Ji-han exhaled, letting his eyes close for a moment. The calmness of the evening settled into his chest like a warm blanket.
He allowed himself to smile—just a little—as he waited for the sound of running water to begin. Then he got up and went to the other bathroom, that is in the guest room.
After Yoo Ji-han finished showering, he returned to the bedroom, surprised to see that Chae Yoo-jeong was still in the bathroom.
He let out a small sigh and lay down on the bed, wearing only a black robe loosely draped over his body. The day’s warmth and emotional weight began to catch up with him, and he felt his eyes grow heavy with drowsiness.
Just as he closed them for what felt like only a moment, a strange tingling sensation around his lower back startled him awake.
His eyes opened quickly, narrowing slightly as he registered what was happening.
“This little brat……”
He muttered under his breath, half-annoyed, half-amused.
He saw Chae Yoo-jeong who was naked spreading his legs widely as he was licking his tight hole to lubricate it. Yoo Ji-han took Chae Yoo-jeong’s face from this awkward position by grabbing his hair. His hole slightly twitched from the missing warmth of his tongue.
“That’s not gonna be enough……”
Yoo Ji-han’s lower body twitched, his face flushed a deep red. Chae Yoo-jeong smiled gently.
“I thought you’d prepared something like this—”
Before he could finish, Yoo Ji-han gently pushed him back and reached into the drawer behind the bed, pulling out a set of dog ears, a matching tail, and a bottle of lube.
“I wouldn’t want to miss the chance to make this moment a little more special.”
Yoo Ji-han said with a sweet but a bit scary smirk as he looked down at Chae Yoo-jeong that seemed to tell that he was planning to bring his everything to the job. Yoo Ji-han took some lube into his hand and poured some onto the tail’s insertion part. Insertion part was a medium size with bumps and 5 circular bobs attached.
Yoo Ji-han carefully reached below Chae Yoo-jeong’s dick and circled and slided down the area before pushing his fingers into it and stretching inside.
Chae Yoo-jeong trembled slightly from the discomfort and reflexively tried to get up, but Yoo Ji-han pushed him down, keeping his hands just out of reach. Although Chae Yoo-jeong usually led a more physical lifestyle, having plenty of free time this year to work out while Yoo Ji-han was often away—he still seemed physically overwhelmed by Yoo Ji-han at this moment. His eyes reflexively closed due to the sense of unfamiliarity entering his lower body as the nails of his fingers scraped inside.
“Shh…… Everything will be fine.”
Yoo Ji-han said in a warm voice, gently petting Chae Yoo-jeong’s hair with his free hand.
He slid his fingers deeper, adding two more and more amounts of lube to stretch it out more. The way Chae Yoo-jeong swayed before him and made soft noises stirred a mix of guilt and sadistic thrill within him. Chae Yoo-jeong’s trembling gradually subsided as he grew more accustomed to the sensation. Yoo Ji-han licked his lips with excitement.
“I’ve always wanted to try something like this…….”
After kissing his cheek and whispering, Yoo Ji-han placed the dog ears on Chae Yoo-jeong’s hair. Chae Yoo-jeong wasn’t able to fully feel the pleasure, as he had never bottomed before. His reactions weren’t much, other than his eyes, which were full of curiosity as to whatever his Hyung was planning. His tight hole was stretched out repeatedly to ensure that he wouldn’t feel any discomfort in the process.
‘I only feel like something unfamiliar going up and down……’
Chae Yoo-jeong’s eyes blinked with uncertainty, as if unsure whether he would enjoy this. Yoo Ji-han only chuckled at the sight before him.
“You really look like a golden retriever. I think the spot for the tail is ready now.”
A metal chain, which contains small spherical balls, about 5 of them, each around 4 cm diameter and the tip base of a cone, was dipped in cold gel. Yoo Ji-han placed them one by one. At first, one ball slipped from the hole, due to how stretched it was, so he placed 3 balls consequently and pushed it inwards to create more space before placing the rest 2 balls. The balls smoothly moved over the prostate, although Chae Yoo-jeong couldn’t feel much.
While Chae Yoo-jeong showed only slight discomfort, unsure whether he would feel anything or not, his entrance felt like it was being squeezed and filled up. He thought at first it would be nice to be filled up like this so he could adjust more.
“It’s cold.”
“I thought the extra cold gel would help you enjoy the sensation better. So, I bought it.”
After mustering a little courage, Chae Yoo-jeong looked and his eyes widened.
Then, flustered, he said. He felt as if something was nearly touching his stomach.
“Is… isn’t it…a bit… too long?”
Yoo Ji-han carefully inserted each ball one by one until none were left outside. The five balls filled up the tight space in the hole, leaving no room for the tip. After making some space inside, he grinded the tip in a circular motion gently with some gel dripped onto the gel.
Sealing the warm hole, the tail fitted perfectly into the right position and wiggled as Chae Yoo-jeong’s hips shifted, which created an illusion as if he actually had a golden tail on him. Yoo Ji-han can’t tell me if he was doing this on purpose or not, but it was so cute either way.
Suddenly, all the balls aligned perfectly inside, as if magnetized. Some sorta chills ran through his spine as if something had started to itch and scratch near his prostate. The pleasure was enough to naturally arch his back, which only brought more, as the sensation started to increase slowly after. His hips rubbed onto the sheets as the entrance itched in pleasure to be touched and arose with it. The sensation was as if all the nerve cells had rushed to the edges of the prostate.
Chae Yoo-jeong moaned spontaneously, as his waist swayed. His eyes snapped shut instantly. Realizing it right away, he opened them wide and quickly covered his mouth and tried to cover his legs, although it was impossible.
“Ngh!! U….Ugh. Ngh……”
‘That felt too loud…… How embarrassing.’
Yoo Ji-han felt a shiver of excitement ripple through his body at the sound. He smirked. His cold dark eyes shook with delight at the sight of him wiggling under him.
“What a cute puppy you are.”
