Jin had two sides, a violent monster and a loving boyfriend.

You were celebrating your Jin's birthday. Just you and him. He lowered his head and blew the candles, the tip of his nose buried in the cake. You reach your hand out and wipe the cream off, his eyes widen at your kind gesture. Not long after, his expression changes. He gets up from his seat and throws a punch at the wall. His nails grew into sharp claws as he pounded his surroundings with his fists. He needed comfort.
