I... think it could be a spoiler to answer that right now, though the main character indeed is having interest in Damian... And about rutes... the story is meant to be linear (as far as it has been planned). The things that might happen in the future will be based on a single timeline, no choices or rutes. I hope maybe this answers your questions n.n'''
As the story is not being written in my native lenguage, and I barely started coding some months ago, right now its kinda difficult to plan multiple alternate universes heheh n.n''''''''''''''''''''''''
