Hey Bruce, thanks for commenting.
So, the mc will have several girlfriends on his journey, but none of them will be in the same place at the same time, maybe once in a while there will be 2 or 3 girls in the same room but they won't interact much with each other, that's why I didn't include the Harem tag, in the game because I think that to be harem all women have to be sharing space in the same environment, but I could be wrong too.
About NTR/Sharing, I don't intend to put that, but maybe the MC will get some married women. ( ͡° ͜ʖ ͡°)
