"They're bi and no one wants them" boring, insufferable,why make them bi to begin with and then say no one wants them. Seems like you're playing it safe not to piss off the biphobes.
"They're aroace and no one wants them" hilarious,it's less annoying, they don't want anyone to begin with. And it's a great way to confirm them being aroace by having them mention that they're really not interested every time someone goes like "Ew,you have a crush on me or something?". Or when someone assumes they're in a relationship with/has a crush on their friends or enemies.
