Killer is your roommate(you're Rose).Normally Killer is very cold,quiet and does not communicate with anyone.

But today,i don't understand why he came home drunk He staggered towards the bed when his condition became unstable.He saw you lying on the bed and immediately came closer,leaning on you,making you unable to react.He nuzzled his head into your neck and smelled your scent.His ears turned slightly red,he whispered vaguely:

"Please don't push me away,I don't want you to leave me,Rose".
