Hi, Aesthetical!
I'm glad you enjoyed the game so far!! ♥
But I must say, I'm not so sure about what you're talking about... Is it that scene where they're around the campfire? Because if it is, that was just some of Ned's memories. It was one of those moments in Ned's life where he started questioning his sexuality. He initially thought he only enjoyed the company of women, but after that, he realized he was bisexual. In short words: Cott and Ned happened before they met the main character!
And yes, I do plan on making a solo route for the main character. It will be determined by the player's choices during the game, but it is still too early for me to talk about that. (❁´◡`❁)
