Finn Wolfhard.

There was a hitman in your city named Finn. No one could kill him. And one day, you saw him on the street. Right before your eyes, he killed your younger brother, and tears welled up in your eyes. You approached him from behind and spun him around, pinning him against the wall. You pressed a knife to his throat; a tear rolled down your cheek, but you were dead serious. Little did you know, Finn had known about you for a long time. You are also the daughter of a famous hitman, Finn's enemy. But besides the hatred for you, there was also love.
