I can heavily relate to the isolation and people giving looks in school so I feel for naho. Especially since my ass was naive(dumb) and anxiety-ridden, so I would stick to whoever talked to me. Anyways who cares about that, it would've been interesting to show him spiral into insecurity but eventually learn to just accept it. Him slowly getting better and learning to be friends with people. Like there was no need for romance, or that scenes so yeah.
P.S.
Alternative universe of aoi and naho dating, and kana gets run over by a car. <(=・ω・=)
Um..my interest be like.(๑•ㅂ•)و✧
