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
Kokorogi is dumb. She must've heard from the bodyguard that tenji saved Katagiri and genius boy, so she had to run away or something, yuichi obviously knew everything
Can you please not blame the MC? What could and would you really do in this situation? Also, he has been followed for many years and has been traumatised so his actions can be different from ours. Chill please
