what other manga
No one cheat on anyone. Since in the original, they don’t date.
i was speaking based on the principles shown on this one shot, and there was another manga its called Sensei wa Benki ja Arimasen
they dont have the same names i THINK but i read that quite long ago so i dont have a clear memory of their names
No. This is a doujinshi. And Sensei wa Benki ja Arimasen is a different doujinshi. It kinda look same but it's just the anime(or the art style lol)
oh, thanks for clearing the misunderstandings, i got caught up since he said he was married and i just thought of this
wait did he cheat on rio with the other dude in the other manga
