It’s not like we created the word seme and uke they r just terms used in bl and they have been used from the beginning. That’s why we use them. Referring a character by their hair color gets confusing because a lot of the time multiple characters have the same hair color. Personally I’m kinda bad with names especially since these r foreign names some of the names don’t stick so people forget them sometimes. Seme and uke is more straightforward. Plus I always hear gay guys refer to themselves as tops or bottoms
That’s because there is no terms to refer to the top and bottom positions in japanese yuris (and yes i know this particular series is korean based but the targeted audience are still the same) We dont say it to fetishize the characters we know this isnt reality. We are just to lazy to type out “The one with brown hair” or their name because we already read enough yaois as it is we get mixed up with the names unless we rlly like a character
Okay I've notice that some of y'all refer to the characters by there sex position and it hella weird and gross tbh like you could actually use their name or say their hair color.
