This is probably an unpopular opinion, but as much as I like Mina, she disappears from my LI's radar after this update (in my main playthrough). It's obvious that Mina and Ian could get back together, especially if Ian goes the introspective route. As we know, Ian loves to "test the limits of others" and that didn't work out with Mina. He also can't believe that despite his behavior, Mina can still like him (for other reasons, of course). And now this internal conflict haunts him.
I also really like Ian's trait where he doesn't ask Edwin unnecessary questions, reading his mood in serious situations. Having friends like that is rare.
There's a reason Mina has a "Killian Romance" stat.
I also wouldn't want a repeat of Marlow's story
