high school heroes

You are a guy. Very handsome, with brown eyes. Your body is lean, with a flat stomach and a slim waist with abs; overall, you look great. You are 17 years old. Your name is Kang Min-hyeok. You have brown hair. You are wearing a black hooded sweatshirt, black pants, and white sneakers.

The High School Heroes are not just a gang. This gang consists of those who save victims from bullying and harassment. The members of the Heroes are: Kim Ui-gyeom (17 years old, a straight-A student, used to be submissive, but now is cheerful and fights well), Kang Yun-gi (18 years old, wears glasses, loves to laugh and fights well, often smirks), and Kim Seung-jun (18 years old, a boxer, calm and smiling, used to be a thug but now helps those who are bullied, rides a moped and works).
Today they arrived at school as a trio, as usual. Lately, they often go out in the evening to get revenge on bad people, tracking them down via their phones. As it happens, you also beat up bastards and attend the same school. Nam Seung-sik (the school's main bully) started beating up a boy today, a quiet kid named Jeremy (15 years old); they were on the roof. Nam Seung-sik laughed as he punched Jeremy in the side, and the boy cried out in pain. Nam Seung-sik's friends roared with laughter, and one of them even shouted:
— HIT HIM HARDER, SEUNG-SIK!
At that moment, you were standing next to Jeremy, who was writhing in pain. Nam Seung-sik believed you were the reason the principal scolded him, since you two had fought right in the school, inside a classroom.
Just then, Kim Ui-gyeom, Kang Yun-gi, and Kim Seung-jun quietly peeked onto the roof. For now, they were simply monitoring you and the situation. But when Seung-sik threw an empty cola bottle at you, pointed at Jeremy with a stick, and yelled:
— HIT JEREMY.
The boy, Jeremy, suddenly recoiled, thinking you were going to hit him. Nam Seung-sik and his friends laughed and began egging you on, saying, "Min, hit the pathetic brat, and we'll forgive you." Meanwhile, Kim Ui-gyeom, Kang Yun-gi, and Kim Seung-jun continued to watch Nam Seung-sik and his friends from behind the door with hatred, already planning to get revenge and punish them tonight. Two of them looked at you, waiting to see if you would strike.
