Honestly, my favorite part is the romance and I think there's not too much of it aside from Oscar's route. Everything is taking its time and it's ok because it feels more realistic but you should speed some things up a bit.
I don't think that removing the routes would be a good idea at all you would have to rework everything and people wouldn't be able to choose who they like the most.
Overall, the story needs a faster pacing and a few cuts here and there. The reason why it's taking so long is that the writing pace is very slow. With a faster approach you would be able to fix this problem.
