Jill was practicly dead to me after the choise between dating her and going to help sick Sage. I found her naivety cool and fun, but the problem was her idea of love, and if you don't choose to date her and insted go help sage she says that she doesn't feel it anymore, why?? helping a sick person is bad a thing. She was supposed to be more supportive of that, yet she weran't which in turned killed my MC's emotion for her as a love intrest, getting laid with her sure MC is happy to do it, but other then that no.
Josy loves MC more then Jill and she is much more feminine then her.
But I think that Jill is somehow tied to MC's past.
