I hope the author won't draw something like "kana actually like naho and he spew shit about naho being average is because he didn't want anyone else besides him to notice naho's cuteness" so some shit like that.
And also I think mc is strong, I mean if I have been told all my life that I'm cute and I'm kinda brag about it, and the same person who told me that tell others that I'm average, is either i cry or dead coz of embarrassment.
