Y'all, I'm aware of the premise, I didn't just pop into the 40th chapter randomly. I know she's inexperienced, I still don't think inexperience equates to just assuming love from every physical encounter. Plus, she doesn't need to have experienced it herself, by college you would be aware of other people's relationships, people dating and breaking up, and also hookup culture. Like, I can fully believe that she is personally inexperienced, I have a friend that didn't date until after college. But that's different than being naive to the point of assuming love in every physical encounter.
This is a comedy yuri harem manga. I feel like you're looking way too deep into this. You're also not taking cultures into account. Not every person is brought up the same. Different cultures play a big part of how people grow up.
I mean, we're on a forum for manga, looking way too deep into things is par for the course. I feel like that's unintentionally putting down comedy as a genre as well. As far as cultures, I don't necessarily disagree but I'm not sure how this applies to this situation. Are you talking about the "culture" of Mei or the author's experience?
To be clear, I don't dislike the manga. I think a lot of the interactions are fun. I don't see why thinking the main character is unrealistically, and to me distractingly, naive is not taking account of the culture, rather than expressing a flaw I find in something I like.
