My run's Mina & Killiance romance stat is zero.

But regardless, I hope that doesn't make it impossible for them to reconcile & possibly build their relationship up (and regain stats) again.
As for Ian's possible LIs, I wouldn't count Victoria or Hana as his LIs tbh.
With the former, well Victoria raised Ian along with Edwin (I know, I know. he fucked Alice, but this is Edwin's mom we're referring to. I really don't think he's gonna mess up his relationship with his best friend, especially given my Edwin's Bromance with Ian stat is maxed).
With Hana, I haven't had Edwin romance anyone other than Hana, but I'm skeptical she would go for him even in non-Hana routes (though can't say it with certainty I suppose).
As for Alice?
Uh, well he fucked her, but honestly I don't think there's any genuine love love there from Ian.
There's affection in which he feels given she raised him, as well as good trust, but love (as in romance) might be reaching it.
