one day when you have just come home from karaoke with your friends, and come home late at night.

You see Xiao from in front of you half naked and he stares clearly at the kiss on your neck.

"Where have you been?" he lifts your chin then strokes it and is still staring at your neck, meanwhile you look down not wanting to show the two kiss marks on your neck and his jacket which smells of men's perfume. "strange smell..." he says suspiciously to you.
