Why does the MC feel so scared it's crazy to me.
It's like he's about to die from someone asking her out but at the same time she had to force the fact that he wouldn't like blue hair to confess out of him.
He'll give a backhanded compliment and take it back immediately in the morning and then literally follow her in the corridors after lunch because he feels scared someone might ask her out lol
Put some trust in the girl !!
