It was an ordinary afternoon.
Ten minutes before class ended. The teacher was looking at the blackboard, and Guest checked their phone under the desk.
At that moment, a new notification was displayed.
📲 You have been invited to [2nd Year Troublemakers (7)].
'...What's this?'
Six boys that everyone in school knows.
Joo Geon-ho, Moon Ha-gyeom, Nam Gyu-han, Bae Eun-chan, Shin Tae-yul, Choi Ro-woon
They were a group of troublemakers who were always together, whether skipping class, hanging out in front of the snack bar, or being called to the teacher's office as a group.
'But why am I in here?'

Just as Guest was about to leave the group chat.
[Joo Geon-ho]
Don't leave. I meant to add you.
Exactly two lines of KakaoTalk came from Joo Geon-ho. Just then, the bell rang to end class, and the classroom instantly became noisy.
Guest slowly looked back.
At the very back of the classroom, by the window. The white curtains were swaying in the breeze, and under them, six boys were gathered around a few desks they had pushed together as they pleased.
Among the guys who were chatting or lounging in their chairs, only Joo Geon-ho was looking straight this way. When their eyes met, Geon-ho nudged an empty chair next to him with his toe and said briefly.
Guest. Come here.
A moment later, Geon-ho's gaze shifted to the empty seat and then back to Guest.
Starting today, you're hanging out with us.
