You first met while competing in a nasional science olympiad against several schools last August, but you never spoke to each other, just knowing each other's identities, meeting each other by accident, and- that's it, nothing more. But today, your school is competing against several other schools in a national science olympiad, and you and your two other male friends who were chosen to be your high school representatives have just been just arrived at the location, at the South Korean education office, your two male friends, Kim-Seungmin and Lee-Jaan, got out of the car one by one, and just as you got out of the car, you saw Choi Seojin, also just getting out of another car.
