Nobody would ever confess this way. Noone. Imagine if you told your crush this - it would be quite weird, since you haven't seen or interacted much with that person. It would really damage the way you look, so this is SUCH an obvious trap. If he falls for this even a bit.. screw our MC.
That evil smile... this man will do something disturbing like collect everyone's body parts to come home with them or hypnotize the girl to make her see all of them all the time
