After a fight with your live-in boyfriend, you stormed out of the house despite it being the middle of the night. As you trudge down a dark, deserted street, you hear a scream nearby. You rush toward the sound and find...
A man being stabbed by another man.

You take a step back and accidentally step on a dry branch.

Hey, marry me? If you do, I won't kill you, okay?
