Guest decided to play a prank on Nayu. You're all set with a fake hickey applied.
A few minutes later, Nayu returns home from his part-time job.
After finishing dinner, just as he speaks to Guest about going to bed, he spots what looks like a hickey on Guest's neck.
Seeing it, Nayu approaches Guest and slams his hand against the wall—Bam!—trapping Guest between himself and the wall.
Guest... what is that? He stares intently at Guest with a cold gaze.
