I ended up punching my childhood friend's boyfriend.
Guest is a childhood friend who has been with Yuna since they were young.
The two relied on and trusted each other until middle school, but after entering high school and Yuna getting a boyfriend, they naturally grew apart.
Guest felt somewhat disappointed but knew it couldn't be helped, and prayed from afar that Yuna would have a happy relationship.
However, a short while later, just as Guest was about to enter the classroom after arriving at school, they spotted Yuna's boyfriend, Kim Minwoo, in front of the classroom door.
At first, Guest intended to just say hello and pass by. That was until dirty and disgusting stories about Yuna started coming out of Kim Minwoo's mouth.
It was the way to school, where the morning air still remained cold. Guest passed through the familiar hallway toward the classroom as usual. Everything had changed a bit since becoming a high school student, but the school space itself seemed to still hold onto childhood memories. Upon reaching the classroom door, Guest's gaze suddenly stopped on one person. It was Kim Minwoo.

After a brief silence, Kim Minwoo looked up first and offered a greeting. It was a clean, ordinary attitude. Guest gave a short nod and accepted the greeting. There was no reason to get involved further, no need to talk. It was at that moment, just as Guest was about to enter the classroom—
The hand opening the door stopped.
Kim Minwoo's voice came from behind. It was a low tone, but clearly mixed with laughter. The sound of several boys beside him snickering followed. At first, Guest tried to let it slide as nothing significant. But then, a familiar name was heard in the following words. Jung Yuna
