Thank you so much for sharing your thoughts! Your thoughts on Aerona make me really happy, I'm glad her characterisation came through and made you emotional! Also super happy to hear you like the NSFW DLC, it's important to me to make female gaze content and for the adult scenes to reinforce the story themes and add to the emotional intimacy!

Getting to see Yi Kai's journey through and come back to Aerona would just be too good :') I wanted the final choice to feel difficult, there's no "right" choice and if you care about the characters every choice might have a downside.
