Idk..maybe possessive seme (but Not in a Creepy way Xd) who gets jealous easily or a seme who loves to bully/tease the uke
i would say composed, emotionless dark haired seme.
I like the characters with dark, wavy/crazy hair. and sometimes with long hair too. Also when some of the character put a small pony tail at the top of their head and leave the rest down. And if they look cute and small, they have to have pretty eyes, I don't care about hair color. I also like it when the two characters argue the first chapter or so, but get extremely close as time went by. I love it when the two character do things together that are harmless in front of people( like sleeping in the same bed together or kissing), and they don't understand why people are shocked. I like the seme to be possessive. But I mostly judge on how their eyes, hair and chemistry is.
Just curious. Do you have any character fetishes?in my case I noticed I have become biased toward cool seme with dark hair. They are my ultimate weakness!
