Not really? Komi and Tadano are great. But then you look at the side characters and it starts to fall apart.>Najima
Oh boy the obligatory trap character. Not only that, but a character specifically designed to be overly energetic and annoying and is the author's personal tool for halting any romantic development between the main couple.>Yamai
Obligatory lesbian. Literally abducts and ties up the MC and threatens to murder him repeatedly. Entire character is nothing more than "OH GOD I WANT TO FUCK KOMI">The dog bitch
So unremarkable I forgot her name. Typical shy glasses big breasted girl, that immediately turns into an unremarkable retard anytime it comes to Komi as she wants to 'be her dog; (why. Just why)>Chuuni girl and Big Sister girl
Actually not bad.
Then you have the new class in the new year and the only remarkable character to come out of that bunch is the Gyaru girl, who is stereotypical but has some likable traits. Too bad she's being set up for a stupid love triangle.
With all that said, the brother and sister are legit god tier characters. any chapter with them together is pure comedy gold.
