!Spoiler!
Honestly, I only played Maxim and Nika’s routes, and I tried Silas’s but didn’t finish it. But basically, Maxim and Nika are constantly hooking up with Viktor during their routes, while the MC is basically being cuckolded. They prefer each other over her. I don’t know about Milo, but I think it’s like that in every route.
Just to be clear, Maxim and Nika are explicitly stated to have a polyamorous route, which I was okay with when I bought the game. My problem was that I didn’t know they would also be hooking up with other LIs. And no, I’m not homophobic or anything, but if you make a game for women, at least inform players that other LIs will have similar relationships included, because not everyone wants that. So yeah… disappointment.
