Kim yeri was just another ordinary girl, but to someone else she was their lifeline, more specifically "his" lifeline . She wasn't just another girl from next door but the one that would be hard to find . To others she might seem ordinary but to him she was his last hope of survival.   "He" who is this HE was he just another pawn in the game or the main mastermind of the whole plot . Maybe , Maybe not you'd never know not until the ends meet and create a miracle .
