She’s been writing NTR and cheating mangas for years, I highly doubt she’s concerned about that. And I don’t even think she does it for the money anymore, it’s probably for the love of the game.
It was already established in the earlier chapters that he couldn’t do anything with his girlfriend because he got aroused after seeing his childhood friend in a swimsuit ( I’m pretty sure ). That reasoning was pretty dumb, but whatever, I could accept it. But now you’re telling me he can...
So he can get an erection from literally anyone except his girlfriend? That’s just retarded writing. Japanese women seriously need to learn how to write a manga properly.
The author finally went through with it. I honestly expected her to back out at the last moment, considering the story had been teasing it for well over 100 chapters.
