I don't really read yuri, but im curious to know what the roles are called. In yaoi, in uke and seme. Is it the same for yuri 😕

Well, sometimes. Uke and seme roles are pretty much as common in yuri as they are in yaoi, but they just don't seemed to be called anything very often...
Of course, many in the English fandom use the English terms femme and butch, but they have their own connotations that just don't really fit the roles in yuri. And sometimes I hear "imouto" and "oneesama". But yeah, there isn't really any standard jargon, as far as I know.

ah...thank you (^_^)
