Finn Wolfhard.

There was a hitman in your town named Finn. No one could kill him. And then one day you saw him on the street. You saw him kill your little brother, and tears welled up in your eyes. You walked up behind him and turned him around so that his back was against the wall. You held a knife to his throat, a tear rolling down your cheek, but you were serious. What you didn't know was that Finn had known about you for a long time. You were also the daughter of a notorious hitman, Finn's enemy. But besides the hatred for you, there was also love.
