oh, Hyao will absolutely give him a good end or multiple good ends. but Everett coming out wouldn't really make Booner's teasing stop because it's not that he likes men that's being used it's the fact he's a MAJOR slut and I doubt Everett will ever go "hey I like getting butt fucked" to all his soldiers/Northcrest without certain situations being manipulated lol.... also, I don't think anyone would believe Booner and the entire thing is mostly just Everett's and Booner's kink.
like if someone who is known as a MASSIVE perv just randomly said "hey the commander of the entire Northcrest army is a slut" would you believe him? I'm pretty sure this is something both Everett and Booner are both aware of, example being how Everett literally says "no one will believe you if you try and snitch" to try and persuade us to forget and ignore what we just saw when we talk to him about the scene we saw, because it's prolly true that no one would believe some rando who appeared out of thin air claiming the commander is a whore. but the blackmail option still works because he understands if we can get evidence due to what we learned from listening while watching, he is still the one in a worse spot because he won't be able to stop Booner because he refuses to actually be secretive and keep his position in mind, and it would be easy to find someone who could help us. a simple example would be Gunnar or Seth/Scar or Jester/Lionel when we return them home and get rid of the... issue plaguing Northcrest. maybe further on if we befriend Lady Tess, we can call her in if we chose the blackmail route if we just wanna expose him.
I'm also pretty sure it's just the shame and stuff that turns them both on. the idea of Everett being ousted and potentially treated as a slut kinda turns Everett on, while Booner likes having such control and being able to fuck Everett how he likes/when he likes.
so maybe there could be multiple good endings and a bad ending that seems "good". the main ending would be Everett becoming comfortable in his interests enough and understanding it has nothing to do with his job and shutting down shit of people claiming he isn't good at his job because he likes being submissive in sex by being an insanely good commander like he always has been. a different one would be he becomes more confident again but instead resigns from his position of Commander because he doesn't want to associate his personality outside of work with the army or something and he just does as he wants while helping Northcrest if needed. the last ending would be the "good" one. this one would SEEM to be beneficial to us and Northcrest because Everett would be become focused as all hell and getting shit done fast, but it would be about him repressing the sexual urges and letting Booner just stay in jail for good. eventually though something would go wrong because he stopped being able to focus at all due to being extremely horny and trying to repress it again which would start the reason this path was not actually a good idea and revealing the "good" just meant bad entirely with almost no one benefiting in the end of it except maybe us short term because we got good stuff out of him or something else.
