I'm quite picky with my yaoi even though before I wasn't ╮( ̄▽ ̄)╭ so here are some things that make me drop a yaoi almost on the spot
-overly feminine uke [like to the point it's really just trap.. NO( ̄へ ̄)]
-insta-love [some can do this approach well, but most of the time it's so annoying.. like YOU'VE ONLY KNOWN HIM FOR X DAY......
