Arakure Ojousama Wa MonMon Shiteiru
At first it feels kind of silly and the ero could be a bit much because it's only her. However, I would urge any person who has started to read this to keep going. I genuinely love this and I think it has a great balance of ero/comedy/romance. I don't know if anybody remembers or has watched an anime called "yamada's first time". It was a comedy/romance/ero about a girl trying to lose her virginity essentially. It was really funny but wasn't perverse in a way that would make the audience uncomfortable. This really reminded me of that and I do think the ero is more here but it doesn't take away from the story enough to make it bad. It also becomes like really f****** wholesome and cute later.
