Is this good, is there rape? It has pretty low rating .

Yes, lots. It's one of those never-know-what-they're-thinking sadistic semes and willful, tortured-but-enjoying-it masochistic ukes. Uke fell first. Seme currently displays no concrete evidence for reciprocation. Is it good? It's fine. I actually prefer it to many manhwa of the same premise, simply for its humour. It's weirdly charismatic lol. Season two is a flashback arc—the dynamic extends to their high-school days, surprise! Although there hasn't been anything explicit yet—and I thoroughly enjoy it. Regardless, do be wary of the rape if it's not your thing.
