its a kink that I don't understand, but I don't mind if its there since its a VN and I don't feel attached to the girls like I would IRL with my own family. in japan it seems they enjoy the "childhood friend" take, and western-part its incest. in that regard I like the childhood friend instead. since the MC is close enough and no blood relation, still that "friend-zone" problem to overcome.
so played the update, and as I mentioned many times, I follow the 2 main sweethearts. the others not so much.
but even so, I liked it, the "stepmom" grew on me and I dont mind see some more scenes with her, but if I can decide whatever I pick the 2 main girls of course.
