You should read ''There's No Way This Is Fate'' and the side story of it. Im literally obsessed
Its not an omegaverse, but it's a trouple called Canis: The Speaker https://www.mangago.zone/read-manga/canis/
i loved it when i first read it but the brothers seem a bit too close thanks for the rec im gonna go reread it
Tbh i liked the sequel (newlyweds arc) a lot better. It a lot more free
sameeeeee and i loved how the brother got together with his butler
I yearn for a omegaverse poly where all of them love each other, not this, where the alphas just collectively hate each other and fight for the affection and love of the omega ToT
