I really like your VN, I find amusing how next chapter is so much better than the previous one. Although I got question that bothered me while I was reading chapter 4.
A bit of spoilers next:
I remember reading that relationships in your VN are more brother-like. But when I started reading Baiyu's route they got much more intimate with each other than brothers would like ever? Does that mean they could become lovers in the future chapters?
