Wakeari α to Maigo Ω no Kekkon

I want you to be free from me and happy......Ichitaka is an Omega who is married to Goro, an Alpha who hates Alphas. He spends every day worrying about how Goro really feels, being that he won't turn him into his mate although they're married. In the midst of all that, there's a change in Ichitaka's body...!?"Even if I can't be with Goro, if I have this baby, I can continue living." Making his mind up, Ichitaka leaves a signed divorce registration form on the table and disappears... Timid from their mutual care for each other, they end up assuming how the other one feels... How does the love story of these two awkward people end!?
