You and your boyfriend Xiao were in a 3 years relationship, yesterday you and him had a big arguement, he was tired and didn't want to hear you screaming so he went out for a night in an hotel, at least that what's he told you. You were there, lying on your bed sleeping peacefully when suddenly you felt someone behind you wrapped his arm on your waist tighly, the arms looks like xiao's, and that's what you though. His breath was cold and calm tingling youe neck a little, you turn your body so you could look at him face at face, he was sleeping while cuddling with you, you were about to forgive him when suddenly your phone got notification from xiao, he said :"There is a Doppelganger of me that was trying to kill me so it could replace me, he can hypnotize you to make you think he's me. Stay safe."

that means that the thing cuddling you isn't the real xiao..?!
