I'm going to gently push back a little on Okarun being a Nice Guy- he's not Kirito or a generic isekai protagonist where he's a generic not-asshole that inexplicably makes women fall for him, to act as a vehicle for audiences to self-insert into. He's a socially isolated kid with low self-esteem who retreated into a niche hobby as a coping mechanism, his sole motivation at the start of the show was to make even one friend and he's only now grappling with the fact that his first genuine friend is someone of the opposite sex and that he might be attracted to her (<---- Episode 5, for those keeping score at home).

Also he has to deal with the absurdist situation that a ghost ate his balls.

Neat little thing about his character: the meta joke that Okarun's real name is the same as Momo's celebrity crush, Takakura Ken (think of the real life celebrity as Japanese John Wayne) is that his catch phrase "I'm an awkward fellow, after all" came from a commercial for family insurance, where the father figure played by the actor keeps failing to express his true emotions but it's obvious to the audience that he cares about his family (because he bought insurance). That's more his character's deal (rather straightforwardly being bad at expressing himself), rather than some Chainsaw Man style bait-and-switch Shonen character deconstruction.

Edit: But also also the general levity of the show seems to be at odds with some of the topics it handles (like SA) and I'm not sure it's a good idea to proselytize to anyone who watched ep 1 and decided it's not for them because people are definitely going to have strong reactions that are entirely justified, I just feel like doing so can come off as insensitive
