I haven't seen any spoilers for this, so I'm hoping the protag and the daughter in law eventually develop a positive bond!! I really like this so far :)
Omegaverse is about heats and out-of-control, animalistic sexual urges. So, even Alpha x Beta still has to deal with the Alpha's rut. To completely escape the compulsive sex, you'll need Beta x Beta and I'm sure no such story exists because that's essentially normal BL yaoi.
Wow I forgot how much Satou pissed me off I need spoilers
