Thank you for your kind feedback. I’m very happy to hear you are enjoying the game (and that you enjoyed TROS, too)
And, yes, there is one more yuri route in addition to Charlotte’s. I've included a picture of her below since I don't think she appears in any of the screenshots on the game page or in Sofia's route (she had a small part in Bastien's)
Vesela Brovik is an Alvardian ambassador at the embassy. She appears in many of the routes and will be a romance option in the ‘Single’ route (the route where you ended TROS without a romance).
So I hope you can look forward to her route as well as Charlotte's. ^_^
Many thanks for playing
