Clannad, Bokura wa Minna Kawaisou Recommendations
For those who enjoy RomCom/SOL anime, I'd recommend Clannad.
The art style is similar.
The storyline falls into the same high-school love trope.
Strong character progression.
The story is about the protagonists efforts to get closer to a quiet and quirky girl.
The way that both male protagonists want to help the female protagonists who are alone to make friends is similar. The way Kotomi and Ritsu are both immersed in their books and loners is similar also.
