beta
but what the fuck is a "alpha mate"?
it's probably some sort of contract between an alpha and beta?! wasn't yeonwoo a beta before? and the sejun father or brother hired the uke for seme because both of them are like the desame? u know " late bloomer "? something like that, even tho the seme hide the fact that he already an alpha,
it's just my guess ┑(￣Д ￣)┍
I'm stil waiting by side stories... please....: (
