ngl i really hope the routes will eventually intersect and we can save everyone. being able to save only one is like being forced to chose between your own children
some games like this have a true ending that only unlocks after you completed all the routes' good endings. will be interesting if they go that way, hopefully without locking into fated pairing like PW or others did.
I really hope this is the case I would love if you get to save one of them and then they get to help you save the next one until all of you are finally united again to all live a happily ever after.
