Thank you for your reply. Now I know what to do.
I have to say — even though I personally would prefer to be the top with Kai, I'm also genuinely glad that Eco finally understands what he wants and has chosen to be his true self.
Coming to terms with oneself is a major life task for everyone, and Eco has managed it in most situations,that's really great.
So I'll just treat my own exploration as a small, private attempt, something that's only on my side. As for Eco himself, he will always be able to choose the option that represents his true heart
