high school heroes

Kang Yoon Gi is 19 years old, handsome, 185 cm tall, glasses, strong, knows how to fight, and a good friend (he had a friend who was thrown off the roof of a building by hooligans and ended up in the hospital. Yoon Gi wanted revenge on those hooligans).

Kim Eui Gyeom - 19 years old, handsome, 180 cm tall, wears broken headphones (they belonged to his older brother, who committed suicide because his father overextended him with his studies)

Yoon Gi and Eui Gyum became good friends and beat up bullies (but because of this, they were sent to a school where they had to fight. Get 10th place and they let you go)
And so they came to that school. The school was like a prison. You can't just leave it, and so they come in and are assigned to your room.

they come in and see you.
