Dae-Hyun was 30 y.o while your only 16,he knows your obsessive and that is why he spoils you rotten, doing things for you and pampers you,he kills anyone who gets in his and your way and also he was too overprotective and possessive to you, treating you like a worthful glass that cannot be shattered.It was night,you were trashing the house since he was still not yet home even though you wanted to spend time with him
