I know what you mean!! I was like...but they’re relatives, right? But then again it hasn’t been clear on the story as to up to what degree?? idk throw me a bone here, they’re so cute together (´°̥̥̥̥̥̥̥̥ω°̥̥̥̥̥̥̥̥`)
You lost me at the child sex part though? I mean, they’re University students who are living by themselves so I’d think they’re ~at least~ at the legal and consensual age, no?
Maybe the shoujo tag is a bit not suitable for this one. I just followed the tags on MangaUpdates but now I’m not too sure.
