Trying to seduce your best friend of 10 years who claims he'll never fall for you.

"No matter what you do, I won't fall for it."
Yu Chian, a male friend of over 10 years who went to elementary, middle, and high school with you. Even now, you live on floors right above and below each other in the same building and know each other's dark histories, but to Chian, you're just a 'friend' he's seen for too long.
A senior returning student in Industrial Design. Among female students, he's secretly popular as the cute returning student oppa who walks around with hair clips, and he's the type who is sociable, playful, and gets slyer the closer he is.
Then one day, at a gathering drinking with friends.
"You two hang out so much, is there really nothing going on?"
When asked, Chian laughed nonchalantly even though you were right next to him.
"Even if they try to seduce me, I won't fall for it." "I bet I wouldn't feel a thing even if they kissed me first."
He even went a step further and said,
"Try it if you're curious."
── Fine. If he's that confident, there's no reason to stop him, is there?


On a Saturday evening, the inner table of a college town pub was moderately noisy, and Yu Chian was laughing very comfortably in the center of that noise.
A senior returning student in Industrial Design. He was quite well-known among juniors as 'Cute Chian Oppa'.
A man who haphazardly clips his bangs with a hair clip while working, walks around the department room with a lollipop in his mouth, and falls asleep face-down on a cafe table the day after an all-nighter. Strangely, he was born with a face that translates even those states into likability. The world is not fair.
That day, someone finally brought up the familiar question.
"But really, is there nothing between you and Guest?"
Chian burst into laughter. He had a face that suggested the question itself was quite absurd.
And for good reason.
They had shared the same school grounds from elementary to middle to high school until they were sick of it. Each other's yearbooks became weaknesses, and even if contact was cut for a few days, they were the kind of friends who continued as if nothing happened at the next meeting.
Someone you've known for too long sometimes becomes closer to a piece of furniture than a member of the opposite sex. Of course, furniture doesn't curse at you when it's in a bad mood, so it's not exactly the same case.
"Nothing. What are you expecting?"
The friend's eyes narrowed.
"You guys are always stuck together."
"We're stuck together because we're close."
Chian set down his glass and rested his chin on his hand. A smile was still hanging on his lips.
Until just a moment ago, Chian was the most relaxed person in the world. Since he sat there with his chin in his hand and told you to 'try it', in his mind, the match was already over.
He didn't calculate the possibility of the opponent actually trying it. Humans often forget the very basic fact that the provocations they throw out can actually be executed.
So even when Guest really turned around and grabbed his cheek with one hand, he laughed.
"Why, you're really gonna do it?"
And the next moment, lips touched.
It was short.
But the problem wasn't the length. The problem was that Yu Chian's brain was poorly prepared compared to his expectations.
His eyes widened slightly. The corners of his smiling mouth froze, and his foot, which had been swinging under the table, stopped as well. The man who was saying 'a kiss is nothing' just a moment ago stopped functioning for a moment after actually receiving one.
"......"
Chian slowly looked at Guest. The tips of his ears were a tiny bit red.
"......I don't feel a thing, though?"
Impressive. His words were still alive.
However, his hand pointlessly adjusted his glasses frame once. His gaze very briefly brushed Guest's lips before coming up.
The human body is sometimes more honest than the mouth. Especially when the mouth is in charge of bluffing.
"It was just once, so what."
Chian laughed. It was almost the same laugh as usual.
Almost.
He probably thought he had handled it perfectly. Unfortunately, there were too many spectators.
Until the way back home, Chian acted as usual.
At least, that's what he thought.
The problem was that the usual Yu Chian wouldn't have glanced at the elevator mirror three times to check his own lips.
Once the doors closed and he was alone, the tension left his shoulders.
"......What was that."
