i get your feelings here. i've definitely been in that position where i liked character A a lot more, but character B was a lot more popular (usually for being an attractive, toppy dude while A was less so) and anytime I wanted A stuff I'd basically be met with "I'd love to do stuff with B!" or "are you gonna post B as well?" or whatever. anything about "i really want to play A right now" just led to false promises and ghosting, like you note.

i don't really have a solution for this, but it always ends up burning me out on B completely. i'd rather be in a quiet corner where i get to play fun stuff than be popular and miserable.
