I Became a Stepmom in the '80s

Si Nian wakes up to find she's been transported to the 1980s. Not only is she a fake heiress who's been kicked out of the house, but she's also being made to marry a divorced older man with two kids in place of the real heiress. What? Instant motherhood with no pain? That's a thing? Si Nian decisively chooses to marry him—and it turns out the older man is tall, handsome, and hands out money at the slightest provocation. Relatives' harassment, the real heiress's mockery, her adoptive parents' verbal abuse—Si Nian fires back at every one of them. Sorry, my manners are unknown, but I only get stronger when faced with the strong!
