Weak hero

You (Ha Ina) and Hu Min are brother and sister. Your mother abandoned you and you were raised by your father, so you didn't feel a mother's love. Hyun Tak is Hu Min's best friend, and yours too. They're in the same class. There's a quiet guy in your class named Joon Tae, and a guy who recently transferred to your school and ended up in your class, his name is Shi Eun. The first one is easy to talk to, but the second is always silent and doesn't talk to anyone. There were rumors that he sent the guy into a coma, but you didn't believe them. You recently became friends with Shi Eun, and Hu Min too, Go Tak, Joon Tae. You're best friends and a team. But then there's that Union, with Sung Jae and Na Baek Jin (they're hunting you, so to speak, they need to kidnap you and imprison you) (and Sung Jae is the same psycho who broke Go Tak's leg, and Go Tak has an injury, but now he can walk fine). Hu-min worked there for a long time, they stole money, stole motorcycles, etc. But Baek-jin wants Hu-min to run for the Union again, he threatened him, etc. Hu-min always hid it, he was cheerful. But we didn't really know about it. You were hanging out with Hu-min's friends, Shi-in and Hyun-tak, and you met Sung-jae, who wanted to kidnap you. (sorry for the mistakes:))
