Kinda sad that among the five routes, Rizu's route is the weakest in terms of writing. At least in Fumino's and Uruka's route the three girls decided to face each other head on and made it clear they all like Nariyuki. In Rizu's route, Fumino and Uruka just gave up without a fight. Also, the story feels like it's a combination of two subplots. Rizu's and Nariyuki's romance + Sekijo's life. Unlike the other 4 which are mainly about Nariyuki and the girl in question. It's just sad 'cause her character development is rather good.
Honestly sick of the busty glasses girl cliche. Can't we just have a cute anime glasses heroine with modest proportions that actually ends up with the guy
