I agree with @Tessa, this NOT rape, not even close, she loves him and wants to have sex with him, it's just that she is shy and he is perverted. But he never actually forces her into anything, well, except for ch4, that part is just sad and wrong, well again, i didn't enjoy it, i saw it depicted as something sad that happens in real relationships, at no point did i see it as something right, it was him venting his frustrations on her, which is just wrong, but it happens.
Leaving that behind, the plot is interesting and cute, the smut gives it something more. I liked the relationship between the two main characters, but i wish it were more equal, though it starts going there by the last chapter, i just would have liked it if the emotional part were more developed.
All in all, cute, smutty, interesting, funny, more or less all that, just a cute light hearted (most of the time, except ch 4) comedy.
