Seems like you don't know yet but some Characters will die or disappear but in my case, some just dies and gets killed by Kylie and I know it's not Necromancy and It's a Harem Game but isn't the point of the Harem Game collecting the girls as many as possible?
Sarcasm is a foreign language to you, isn't it?
I am aware of Kylie murdering other characters.
I'm also aware that despite this being a harem game, not every girl is going to be available to you, in the case of Kylie or Camilla. Its either/or. There's no having your cake and eating it. Kylie is a psychopath. Its pretty much telegraphed to you almost immediately and if you choose to engage in a relationship with her, well, there are consequences.
This is a harem game, but its also a game where actions have consequences. Cheat on a girl? You're gonna lose her. Date the psycho, you're going to get tasered and sexually assaulted. And if you don't get her locked up, she's going to murder someone.
