I'm kinda confused at the ending but loved it anyway

i think what happened is that otaku-kun over here manipulated our precious todo-kun.

it seems like everyone either knew about a todos small pp or actually thought he was a good guy, and otaku-kun knew all of this. he used the fact that todo was insecure to manipulate todo into a relationship with him, and I also assume that he shaved his pubic hair off so that he could get todo to trust him more. but the shaving part is more of a theory that I made.

in the end, otaku-kun needs to go fucking die. he could’ve just told todo-kun hey, everyone knows u have a small dick instead of sexually conditioning todo and then raping him

I was shook. I liked him in the beginning but that took a left turn and I immediately was put off. He's literally did as you said, he shaved himself and made it seem like he had a problem and used Todos insecurities against him. He knew he was well liked by his classmates and probably knew that he was struggling with a small penis and didn't spread any rumors and he was also well liked by the girls. You also see that the delinquent guy picked up a book but it was translated what it was, and I think he knew otaku guys "secret", whatever it may be and I think tried to protect todo but I don't have enough information for that inference. But I do think he was trying to look out for todo! But then That sunovabitch otaku guy whose name I forgot by the end bc he pissed me off actually drove todo into a corner, deciding not to tell him he has nothing to worry about as he is respected as the class president but instead let him eat himself up inside then raped him when he felt he wasn't going to be able to be around him anymore and I'm just donnnnnnne. This is some psychological shit and needs to be tagged with Drama and rape smhhhhh I'm done they had in the first half but man I need another manga to wash this out
