It isn't a very bad manga, it's mediocre honestly. It's moderately enjoyable.
The thing that makes this mediocre is because this development is super common everywhere. Ugly girl x hot popular guy. Already read a couple thousand development like this (I'm exaggerating. I'm sorry. Don't attack me.)
What makes it unique tho, is the fact that they made the girl actually ugly this time. Usually, in shoujo, the girls are always pretty. No matter who they are. (There ARE exceptions tho)
In any case, it's still enjoyable story-wise. There are a lot of details that are nice. You can somehow relate to Tabata unlike many shoujo mcs (Not always tho. Tabata's a bit... extreme...)
In any case, I don't dislike this. It's moderately enjoyable. Will read and recommend.
But, does anyone know if there's a manga where the mc is ugly and doesn't care that much about it? ;-; like, i get it. Being ugly is not nice. Nobody wants to be ugly. But being ugly doesn't mean you have to hate yourself or not like yourself or be so negative and have no self esteem or self worth at all yk... I can relate to these mangas sometimes... but they make me have this feeling that just coz i'm ugly, i hate myself and have zero self worth and self esteem and that makes me very sad
