Don't worry for your English, :D okay! you mean one-on-one monogamous relationship. I focused the game on getting the characters to know each other, having a relationship, and gaining experience, because Ethan is still very young.
He needs to figure out what he likes and what he doesn’t like and deal with, so we’re gonna deal with it. Remember that Ethan is not human, but don’t lose hope ;) and I won’t say anything else. Thanks for the nice words and the fact that you like the game :D
