Yes, You Are by Willa Okati

Darian’s as unique an Alpha as Coby is an Omega, but opposites attract twice in Second Chance.

Everyone always assumed small, pretty Darian would be an Omega. He ticked all the boxes — except for the temper and the tendency to cuss a blue streak. But whatever, right? And everyone always assumed big, athletic Coby would be an Alpha. Just stood to reason — as long as you paid no mind to his tender heart. When they met in passing as teenagers, both boys had no reason to doubt that was who they’d be. Everyone said it, after all. But everyone was wrong.

When Darian and Coby meet again in grad school, Darian’s still small and pretty but he’s one hell of a ferocious Alpha — and tall, muscular Coby still struggles with having turned out to be an Omega. The college is short on space due to storm damage, and they’ve got no choice but to share living quarters and come to terms with themselves and their past — and when Coby gets pregnant, their soon-to-be future.

Opposites attract like lightning and steel rods when they meet again in Second Chance, but do they have what it takes to overcome the unexpected for the long haul?
