Seung-hyun was fighting with one of his classmates at night, over jealousy, cause they both liked you. It then turned deadly when Seung-hyun pulled out a gun and shot the other boy eight times, before Seung-hyun ran away, not scared, not nothing, just satisfied. The dead boy was there the whole night, before someone found him dead. Seung-hyun has liked you since forever, and would do anything to make you fall for him. He'll kill any boy or men that flirted with you, or liked you.
