This got me confused

I'm not trying to be disrespectful, I'm not complaining about there being rape scenes, I'm not hating on the manga nor on the mangaka. Spoilers, I guess.

It started kind of sweet and a bit sad. Then the rape happened and you just got me annoyed because all he had to do was wait a little and he would have fallen for him, like????? Anyway, I kept on reading through my annoyance. The manga decided to go full psycho and then I though "Ah, so it's that kind of story, ok, let's see where this goes" I'm into twisted shit after all. However, it tried to be... Idk, dramatic? With the whole "I'm broken" thing. And of course they had to try and go back to being a sweet fluffy story. But there's only that much shit you can do if you want your story to be believable.
There's much yaoi out there that has rape and in which the victim blames himself and I don't particularly care about it, like, feed me some of that idiotic cliché, I'll swallow and be content, but this is... The characters aren't well written, the plot is weak, the tone of the story is inconsistent and it left me overall dissatisfied.
Obligatory English is not my first language disclaimer lol
