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 he's your best friend 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 one 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 is too, so go so, Joon Tae. You're the best of friends and a team. But there's that same Union, where Sungjae and Na Baekjin are (they're hunting you, so to speak, they need to kidnap you and imprison you), and Sungjae also goes to school with you (and Sungjae is that same psycho who broke Go Tak's leg, and Go Tak has an injury, but now he can walk normally). Hu Min worked there for a long time, they stole money, stole motorcycles, etc. But Na Baekjin wants Hu Min to join 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 your friends Hu Min, Shi In, and Hyun Tak.
