[Yeonjun fanfic]: His first love

4)

“Han-nyang. I don’t get this.”

Yeonjun had a pen in his mouth as he leaned toward Yumin’s seat.

“Haah…”

For Yumin, the library was a pleasant, refreshing place that helped him focus on studying. Unless there was a troublemaker, that is.

Yumin couldn’t understand why he was teaching this loser study on such a golden Sunday.

“I’ll explain it just once, so listen carefully. ...Look, if we introduce this into this function...”

Because he was sitting by the window, the summer breeze came in and lightly brushed Yeonjun’s bangs back.

It felt like just a few days ago people were definitely out enjoying the cherry blossoms, but suddenly the weather turned warm.

Seeing Yeonjun with his brow deeply furrowed as if he were completely absorbed, Yumin decided he might actually have some potential. Contrary to the rumors that he was a crazy bastard, he was pretty well-behaved.

“-So since every function satisfies this property, you can’t just declare one answer to be the only correct one.”

“If there’s no right answer, then why are we solving this problem?”

Yeonjun, who had been listening quietly the whole time, objected in a dissatisfied tone.

“Then it doesn’t matter if we don’t solve this one.”

Yumin slowly tied up her hair with a cherry hair tie as she mulled over the question.

“This is a problem about learning that shapes or functions with certain properties aren’t unique. It’s similar to how we learn by making mistakes.”

“...What if you don’t learn anything even when you make mistakes?”

When Yeonjun asked his answer seriously, Yumin let out a faint puff of laughter, looking a little amused.

Yeonjun stared at Yumin like that with his eyes wide open.

“W-why are you laughing?”

“Just because. Anyway, stop it and keep solving the problem.”

Yumin thought, Choi Yeonjun is a weird kid.

He should just keep doing dumb delinquent games, so why is he suddenly studying?

Last time, on a rainy day, he had crouched there pitifully and cried,,,and now he suddenly asks me to teach him. But he also seems surprisingly sincere, so it’s kind of hard not to pay attention to him.
