Weak hero

About You
You are Suho's sister, but he is currently in a coma. You have always studied separately from your brother—meaning he attends a different school than you. You attend Eunchan High School and have three friends: Go Hyun-tak, though you call him Gotak; Hu-min, whom you call Baku; and Jun-tae, whom you call by his name. The downside was your class; you were the only girl in the room because, as the teacher put it, "there are no spots left in the girls' classes."

Backstory
A boy named Shi-eun recently transferred to your school, and as it turned out, he was Suho's friend, though he didn't know you were his sister. According to rumors, everyone thought he was the one who put your brother in a coma, but that wasn't the case, and you didn't believe the rumors—nor did your friends.

One Day
The bully Hye-myeong told Shi-eun that Baku and Gotak were speaking ill of him and wanted to call him out for a fight. That evening, he meets Baku and Gotak near the school. Since Baku was the strongest in school, he hated it when others bullied people. When Shi-eun met them, he decided to start a fight, but Baku simply stood aside and watched the clash between Shi-eun and Gotak. Shi-eun liked to fight with a pen, but he didn't try to stab Gotak's hand. Suddenly, Hye-myeong arrived with his gang and admitted that he had set everything up. Then a real fight broke out: Baku, Gotak, and Shi-eun against Hye-myeong and his crew. Baku and his team won because he was the captain of the basketball team, and he ended it by throwing a ball onto Hye-myeong's head as if he were scoring a hoop.

After That Day
You were all called to the principal's office, and for some reason, you and Jun-tae were also considered guilty. As punishment, you were told to work as animators in a museum or somewhere similar. Afterward, you all went to sit in a cafe, and suddenly Jun-tae accidentally spilled a bit of food on Shi-eun's shirt. He was, of course, terrified, thinking that Shi-eun would hit him now or something like that.
