I don't understannd the high rating either....in other mangas everyone yells rape for much less than this, yet here, where actual rape happens, no one bats an eye... There are soooooo many better mangas out there, why this boring cliché with a typycal weak uke and a pushy asshole seme is praised so much? Why is it that always the shitty mangas get the anime adaptation? (Given is an exception, THANK GOD they finally choose a decent story)
The thing about ratings, you can only rate a manga if you keep it in your library. So ones like this with a specific audience get higher ratings than something decently popular with a few flaws. (People who love it will rate it highly and there will be mediocre votes dragging the score down whereas this will only be saved by people who love it and aren't bothered by the content and have ridiculously high scores)
The only reason this manga has a high rating is because anyone who cares that it is 100% rape dropped it like a hot potato. I'm just putting this out there for the people like me who aren't into that who might like a warning before reading.
