really love the game so far. not sure if its a bug, but if you break up with Kate because she wants to keep your relationship a secret (for me day 58), Violet will appear in the cafe the next day (for me day 59) acting very jealous of Kate, even if you only went to lunch with her once and nothing else. think this is a bug because the MC says something to the effect of "not being able to live my double life much longer" even though I'm not in a relationship with either of them. Also, Kate's story is so heart wrenching if you're not nice, makes its hard for the completionist in me to be mean to her, really well written.
Edit: apparently this can happen even if you don't break up with Kate. wasn't able to replicate it but when it happened I got the normal end of play through instead of the current end of Kate route
