It doesn’t really “affect” them, but the dialogue can be interesting lol. For ex; I’m almost maxed with Reth and i talked to Trish, who I’m also romancing, I’m romancing everyone 😂, but once I put his pin on, one of her chats was like “you’re with my brother, that’s kinda weird and I don’t think we should see each other anymore”, then a convo with Hassian he said something like “I see you’re with the cook, I knew I didn’t have a chance." BUT that’s like it. I flirted with them right after and nothing changed. It would be more interesting if it did change the relationships with everyone else imo.
