Human!Flippy/Fliqpy x Flaky Killer Love

In the town of HTT, which is full of dangerous and murder, there is a certain girl named Felicia Percy Holmes. She was a shy, timid, quiet girl. Most people call her Flaky, for short, because of her unique hair, which was blood red and had little white flakes that were naturally sticking on along with the roughness of the hair. Despite her shy and caring attitude she has a little... well lets say... messed up in the brain problem. Her bestest friend is a boy named Filip Tony Parker{I don't know where these names come from I'm just making them up?}. The others are afraid of him because he is probably the main one who brings up their everyday deaths in the little town, and that's where the nickname Flippy comes in at. One moment he's the nicest person you could ever see in your life, then the next you is in a danger zone and have to scram before he gets you. This is all not entirely his fault though, he has PTSD from going to war a few years ago, which causes him to have this personality split. One good and one bad. But if Flaky the shy, timid, and quiet girl knows about this other side, why isn't she afraid like the others, why doesn't she just stay away like a shy girl is supposed to and leave him alone not wanting to be killed. Well like I said... she has a messed up in the brain problem...
