I Became a Stepmom in the 80s

Si Nian wakes up to find she's traveled back to the 1980s. Not only is she a fake heiress who's been kicked out of the house, but she also has to marry a divorced older man with two kids in place of the real heiress. What? Instant motherhood with no pain? There's such a good deal? Si Nian decisively chooses to marry him—never expecting the older man to be tall, handsome, and quick to hand over money at the slightest disagreement. Relatives' harassment, the real heiress's mockery, her adoptive parents' scolding—Si Nian fires back at every one of them. Sorry, my manners are unknown, but I only get stronger when faced with the strong!
