How My Daddies Became Mates Vol. 2

Kuroga Akane and Shirosaki Aoi have come a long way from their days as teenage hoodlums. Mated and passionately in love, they've started new lives together in college. Everything seems to be going great - at least, that's how it looks on the surface. Deep down, Shirosaki can't help but worry that he's not the best match for his talented alpha partner. So when another alpha with a dubious background tries to steal Shirosaki for himself, it's up to Kuroga to prove just how strong their bond really is!
