this might sound funny but bl mangas where both parties already know that they are gay at the start of the story/before meeting each other (preferably stated in the dialogue) like no self discovery/gay awakening because they already knew what they like if that makes any sense (??) i wanna skip the self acceptance arc
no age gap + preferably adults + green flags please
