a girl lost her sister at a car accident, she was sad devastated, ruined blah blah blah. When they proceed to the funeral, she saw a man, the man always shows up there to clean after the funeral ( i guess he clears up all the tears and shit idk) ok so the girl INSTANTLY fell in love with the guy, she completely forgot the fact that her sister died, but once the funeral was over she never saw the man again, a week passed and the girl killed her brother. why did she kill her brother?
