The uke is bigger and the seme is small since he is a rabbit and both are gentle with each other. Just a cleansing palate for you if you wanna.
Scent spark. The seme is a baby boy honey bee. He's taller, but the omega is really buff.
BWAT's new manhwa is also like that and it's really cute so far.
Dirty high, seven sunday, I think this author's other works also have bottom being the buff seme and I think bwta also have some manhwas like this.
I hate how tops always have to be bigger then the bottom and if they're not and are presented as cute then they have to be sadistic to kinda make up for it...and yes I know it's all misogyny and patriarchy but I'm tired
