Wow the manga completely changed direction with that chapter 9 parts... I never would have expected such a graphic rape scene... Like seriously, this looks straight up pulled out of a rape doujin...
It started so good too, cute and all, wtf happened to the wholesomeness. It was already weird when she suddenly kept flashing him but this is just way too much change...
The ending is trash too...
Basically a pretty cute series with very helpful tips that got axed and so the author went full hentai with a rape scene and a shitty conclusion...
