Hi there! Thanks so much for your comment and for playing <3
Sorry about the confusion! Every human in the universe except for Seers (Who naturally get their eye colour) have soulmates~! The Seer thing is missing from the game right now because I didn't have time to add it in, but it should come for the next update!
The thing is that soulmates aren't really a 'good' thing in this universe (Even though people are morally obligated to marry them, as you've probably gathered) as you'll kind of see through the game. The title of the game may kind of help you see what I mean by the end~!
That said, If you're worried, I can say that no one will get mad at you for whoever you choose. Basically as long as you romance someone, there's a happy ending <3
I will say that Creed's route is severely lacking in CGs (By that I mean there are exactly none) and I'll be fixing that for the next update I hope!
Thank you so much for your comment~ Have an amazing day! Thank you so much for playing :)
