It is fully avoidable yes, you can just be friends, up to you. No straight scenes in the prologue, but there will be in future chapters. Future tags are still up in the air, multiple penetrations will likely happen with toys since this game is not about sharing but like i said, pretty much most future tags are still up in the air.
In the prologue its the possible LI only, but in the future MC will be as well as she gains more confidence, right now she's still really out of her element, plus the memory loss affects her personallity as well somewhat. As the story progresses, she will be gaining more confidence and personallity changes which will lead her to be more bold towards Clara as well.
Damn, some of you guys really are riding on those future tags. As i said before, those are all up in the air, most likely won't even happen. I just put them there to see what people think but honestly if i still had thread ownership i would probably just remove them. I kind of jumped the gun on those to be honest. Anyhow, once and for all (hopefully), there wont be a harem or cheating, multiple penetration tag reffers to penetration with toys. There will be side characters yes, but none of them will be either side girls/guys or main LI's except for one guy who hasn't been introduced yet and who you can only have a romance path if you are not with the female LI. I never said there will be side LI's. To clarify, there will be 3 more girls introduced later down the line, 2 of witch will be only friends to the MC and one just a plot device, and 2 males, one will be the main villian and one will be the male LI. Also, this is a horror game, people will die. You can speculate on who or how, im not going to spoil it because its going to be a big deal, but lets just say that revenge plot is one of the possible paths. But thanx for the feedback, all i can say i can only hope people will like what i have in mind for the story, i understand that it won't be for everyone and that should be fine. Im not going to change my vision i have for it just because some people don't like this or that or want this or that in the game. I can take some suggestions as long as they don't conflict with the overall story too much and fit my game. Harem, cheating, gangbangs etc does not fit. My game is not your typical vampire game, i intentionally want to try and do something other people haven't done. I played a number of vampire themed vn's and most go for the same tropes so i want to avoid falling into that pitfall and instead make something of my own. My intention has never been to please everyone, but hopefully at least some will like what i have to offer.
