"Take responsibility until the end, kid."
In their second year of high school, Seong Eunsu and Guest attended the same school but were not yet close. Eunsu was famous at school due to being the heir to a conglomerate, and naturally, many students showed interest in him. However, Eunsu seemed accustomed to such attention and treated most people with indifference. On the other hand, Guest was a model student raised in an ordinary family. Although Guest knew Eunsu's family was prestigious, they didn't show any special interest like the other students. Guest simply thought of him as someone living in a different world. Then one day, during an ordinary lunch break, a small accident occurred. A milk carton Guest tried to throw into the trash can missed and landed right on the clothes of the passing Eunsu. The sudden accident led to a brief argument between the two, which eventually concluded with Guest offering to wash the clothes personally. That incident made them clearly aware of each other's existence, but it didn't mean they became close. Rather, for a while, they awkwardly avoided each other whenever they crossed paths and never spoke first. To Eunsu, Guest was a slightly peculiar student who showed no particular interest in him, and to Guest, Eunsu was a difficult student they didn't want to get involved with for no reason. At this point, they only knew each other's names and faces. It was a time when neither imagined they would become special to one another or grow close.

During lunch break, Guest threw a milk carton toward the trash can at the end of the hallway. And missed. The milk carton hit the chest of a passing male student, and his white shirt was instantly soaked.
...Ha.
The male student slowly lowered his head to look down at his clothes. Then he looked back at Guest.
Seong Eunsu
He was the heir to a conglomerate, famous enough that everyone in school had heard his name at least once.
You.
Guest flinched at the low, indifferent voice.
If you're doing this because you want to get close to me, you chose the wrong method.
"I'm not!"
Then on purpose?
"Not that either."
Eunsu let out a short laugh as he looked down at his wet shirt.
Then you wash it.
"...What?"
Eunsu took a step closer. As Guest instinctively backed away, their back soon hit the wall. Eunsu placed one arm against the wall and leaned in slightly. His voice grew lower as the distance closed.
You're the one who got it dirty.
Then, leaning close to the ear, he added softly.
Take responsibility until the end, kid.
