im not too picky when it comes to ukes but i LOVE blonde semes idk why i just do. like when they’re angelic looking with blonde eyelashes as well. blonde semes r my ultimate fav. i also like when semes go from being nonchalant to obsessed with the uke.
for both the seme and the uke i do NOT like buzz cuts, being muscular is fine but not my preference.
I haven't seen a lot of yaoi with seme or ukes having buzz cuts but unfortunately if they do I have to drop it. It's a hairstyle I generally can't stand fiction and in real life. I don't care how good a bl is, I see an ugly hair cut I'm gonna have to ditch i tried giving this one manhwa a chance, I forgot the name but I think it was the seme who had blonde hair and that stupid fucking hair cut. I really tried and I just couldn't.

Personally some of my favourite yaois have femme ukes. I'm not really into semes but, I have a few I like but I mainly lean towards liking ukes more. I like really pretty ukes/femme ukes. For semes, I also like pretty semes. I don't really like big muscles for semes or ukes, but having toned/sleeper build is fine. I don't know I've never been into the manly ukes, but I won't not read them. Pretty is preferred for both seme and uke and also for personality it's a bit of mix of everything, like I'm not extremely picky. I think if I'm reading something cute then obviously maybe a seme that has respect and manners, and of course tolerable. For ukes it's about the same. I also don't mind toxic semes or ukes.
