Both characters have no real redeeming qualities; the MC is just a boring typical shounen romance main character, he only began to like the girl because he thought she was cute when he first met her so nothing deep or substantial going on there. The girl is the opposite of emotive, which in itself could be a interesting as a character flaw through which her redeeming features are shown but it seems to be the only attribute shown for her so far. And then there's the fact that the central theme is that she's not a virgin, which could be a refreshing central conflict of sorts seeing as 99% of heroines are explicitly virgins for some reason, but the majority of the time it's only brought up in the MC's inner monologue where he thinks about it every chapter, and then dismisses it in the next thought. It was brought up once in a classroom scene where she's called a slut and whatnot, but the conflict in that scene was mostly the MC's inner turmoil over how he wanted to defend his girlfriend. And because he's a typical MC he just sat in the corner and thought about it for a while and the conflict was resolved with the girl coming in to invite him out. No development of the characters in sight so far, the characters backstories and personalities are pretty bland, the dialogue between the two is bland, the events so far have been bland, hopefully this is just a set up for something with substance in the future because this barely borders on empty fluff right now. End rant.
