That's part of why I love this game, as I think the player will have to make hard choices. Too many games you can just coast through and pick options and end up 'happily ever after' with everyone happy and dancing off into the sunset holding hands and in love.
On the Charlotte path, Lucy has a LOT of really sad scenes, as you have to turn her down multiple times. How she always loses out to Charlotte and everyone else around her. But once the MC starts to affect Charlotte for the better, Lucy openly admits to herself and Charlotte that the MC is bringing her back to her old self and how happy Charlotte looks to be. Lucy resolves to make it work for the MC and Charlotte. Same with Emma, where she wants MC to be her Dad and for them all to be a family.
Suzi will be interesting to see how that goes, as you can only get 2 points towards her, with lots of chances for negative points. So she'll need some concerted effort in the upcoming scenes to improve her status.
I didn't come across any chance to romance multiple LIs. Sure you can get with Kaylah and Fox, but as side interests will that have an effect on the LI options going forward? Kaylah always tells Charlotte if MC accepted or declined to get into a sexual relationship.
Or did I miss getting multiple LIs? Once I've 'locked into' a path it only goes down that route.
