SPRD-1119 - Mother's secret life, I take over

I wish they'd leave out the liquor store guy and just focus on the son and mother. This series is so close to being great! It's a rare series that actually has a daughter-in-law character, so they should really lean into the 'secret affair' aspect. I want a series where they already have a history, and he takes her back to his parents' house, sneaking around to have sex in various spots and situations while hiding it from the wife.
