If there are then they're all slipping my mind. Except for that thicc classmate from early on, she's the only one I can remember who barely got any attention. I remember there was one teacher who had a thing for Mia, maybe she could also be interested in some of the other students.We haven't actually hooked up with everyone, there's still many characters that have had zero or very little content, but I share exactly the same sentiment, having more characters intertwine and interact with eachother would be great for many reasons, especially potential scenes and general liveliness of the game.
It's never happening though, at least on the scale we'd like to see. DC is already having a hard time with isolated questlines.
Has DC said he's having trouble? I'm sure there are a ton of people who'd be happy to come help with the writing if necessary.
