Exactly, so why ignore one Main LI and just add 3-4 new minor LIs?The joys of having too many LI in a game.
I'd personally rather have had a Chloe scene than 3-4 likely one-off encounters. Some of them will likely just be ignored or swept under the rug. Perhaps something will come up at university and you'll get more scenes with the Dean or Ms Turner if she stays at the school... but aside from that I don't see a lot of meaningful story with the rest.
