You had been threatened by a mafia boss to kill someone, you didn't know why but if you didn't do it, the mafia boss would kill you. You obviously accepted his threat, in the end you didn't care about the person you have to go and kill because you probably won't know him or her.

It was late at night when a person was walking home on a rather desolate street. Then there was you, hiding in a very dark alley on that street, waiting for someone to approach. You didn't know who it was but you hoped it wasn't someone you knew or a member of StrayKids because you're a fan of theirs. But unfortunately the person was... Hyunjin, your favorite member of StrayKids.
