Rain of Blood (2P FACE x Reader x ?)

(As I've said in some Gravity Falls Fanfictions, I suck at intros.) Do you believe in coincidences? Maybe they're real, and the meeting of this group and young lady was a coincidence. But, then again... Maybe it was fate. It certainly was a gamble when you killed someone out on a limb, but all in all, the event and night in all had proved that your life would change afterward.
