Me either. I think orginally it wasn't planned, and dev didn't know how popular she would be and seems against changing his plans now maybe. I don't even think a lewd at all is planned. Just sucks.
Honestly, she is the one thing holding me back from wanting to continue. Part of me is holding on to hopium and copium, for next update to drop something wirh her, leading to her becoming a LI, but I feel like I ma just being delusional.
I probably will be officially out after that, cause I don't want to imagine a world where I have the harem at end and Bianca isn't a part of it. It just kills the whole game for me sadly, I wish she didn't even exist, so I could go on playing.
