Suzi is a little different from the others, as your relationship with her is more of a love/hate dynamic. Because of that, I don't think it would work as well if she were too likeable at this point.I give it to HillsideVN , I found myself in love with Lucy, Charlotte and Emma, I hope the story brings a spark to find it for Suzi too.
It feels that MC is the one Charlotte Needs, Lucy is the one that makes sense/Canon, you know it?
And in Emma path is that pure raw fantasy trope, a little wrong but nevertheless I love Emma.
I cant say much about Suzi yet, tsundere olympian.
That said, I’m planning to make some changes to help us at least understand her a bit better. And she’ll probably undergo the greatest character development by the end of the story.
