Lol i know that guy is an omega, and that dude with glasses is an alpha.

no actually they're both omega

What in the world? So who the seme is? never read a manga with omega as a seme, or there will be a love triange with some alpha later in the story?

there is an omegaverse story with a seme omega and an uke alpha, can't remember the name atm tho

found it

Thanks for the manga suggestion, but damn. An alpha uke? Omega seme? Yaoi never cease to amaze me lol (￣∇￣")

So who's going to top and who's going to bottom? :O
