@no168_92 .. well yeah but they are still in highschool, no serious romance probably only foolings around or uncertain about many things.. so no doubt they dont have a courage to tell their parents..
I must confess. I'm one half of an actual fraternal twin pair and I kinda have something kind of like a teeny crush on my brother for a while in my early teens. I guess it could happen during adolescence when we're all confused, but since we're actually blood-related twins in my case, I grew out of it. Personally I think Nao and Kouki might have gotten over each other soon too, if it weren't for the reveal.
i like this in the same way that i would read gay manga, having it be like, not *Not okay* but looked at wierdly and making it sort of forbidden makes it super interesting.
