When Haruka was small he was kinda crybaby and different for an Alpha so they abandoned him to his grandma to take care of him, never visits him until the grandma died when he's a teenager and that's when they decided to get him back. And when he lives with them, the trash alpha mother force him and control him of what he should do and shouldn't do, and doesn't appreciate what he loves. Until he met his mate and decided to elope with him. They haven't reached out to him and his kids until the accident meeting. Seriously I don't think they deserve to be part of their lovely family. Should've keep their distance since Haruka is already happy. Though that didn't happened since the uke tried to reconcile them and Haruka still wants recognition from the trash alpha mother and he forgives her.
