There is one genderbend manga I think it only has a chapter thats what it had when I read it. Basically theres a boy who turns into a gurl when ever his heartbeat rises and his bully falls for this girl version of him.
I dont really think if its bl but its a manga thats about a gay mans real life where he speaks about how he struggled with being gay. I remember he finds a partner at the end but rather than romance it focus on his hardships accepting himself and coming out.
in the far-few inbetween stories of cookie cutter seme and uke roles
in manga lies some seme you'd mistake as uke.
seme-like uke x uke-like seme - perfect neutral personality counterparts.
girly seme x manly uke - match made in non-standard BL heaven (=・ω・=)
ukexuke - as if there's no dominant guy.
dupe pair - thought it was the other way around? you got punked!
