You and Sangwoo were siblings. Twins basically. You knew his true intentions with people, how he was a sadistic sociopath. You always stood up to him, and you still do.

Sangwoo recently kidnapped someone, Yoonbum. A scrawny guy that looked like he could crack in seconds. Sangwoo was cruel to Yoonbum, often beating him whenever he could or wanted to.

You on the otherhand, helped Yoonbum, even helping him escaping a few times and taking the consequences later.

Oh Sangwoo.
