Extremely annoying. The MC is quite possibly the worst main character ive ever seen, being simultaneously annoyingly lecherous and pervy (basically seeing his new GF as a piece of meat for the large part of the early chapters) and annoyingly a pussy (refusing to do anything even when his girlfriend borderline sexually assaults him asking to bone). His main goal is to end his virginity, yet purposefulyl declines every reasonable chance his girlfriend throws his way.

His GF Yume-San is a very kind, nice, empathetic (obviously extremely attractive) and understanding person, while he offers nothing. Obviously this is a simple trashy escapism manga, but usually in these type of harem romcoms the MC is a kind person who the girls fall for for a reason. Here, no attempt is given. Yume is basically a perfect girl who falls for the schools incel head over heels for basically no reason. While he continues to act like either a weasel or a sex offender, she takes it all on the chin and accepts him wholeheartedly, which is wholesome in a way and extremely annoying in another.

Other then her there are a myriad of other girls just there to offer fanservice (the mc is already in a relationship after all). Theres his childhood best friend whose a childish bitch (refusing to befriend one of the mc's friends because he was 'too fat'....), Yume-san's lesbian best friend whose just there to throw a wrench in things, and the school popular girl who falls for him for also no reason, who is a femdom.

If you enjoy not thinking about things and dont get annoyed at cliches or bad romcom manga writing, this could be enjoyable. The main girl is great and so is the fanservice. But dont expect a single inch more then that, or any significant well written fluff moments.
