Spoilers!
I am kinda afraid of where Chester's route could go, specifically about Eddy's romantics feelings not being reciprocated by Chester.
Because its not something Chester wants people to know about (could change maybe) and maybe their open relationship is only sex-opened but not love-opened since he didnt say anything about love.
I would expect (as a player of a VN) for them to end romantically together, but in this route it not something easy to do in a logic and satisfactory way. We'll have to see, absolutely amazing update, it made me take a lot of breaks between scenes because they were so good.
Keep at it!
