Mu Peiqi, a girl from the future, comes with a System and transmigrates into the body of the seventh daughter of the Wan family. She expects a miserable household life like the ones in melodramatic novels, with a grandfather who doesn't care and uncles who don't love her. Instead, her father adores her, and her six older brothers take turns “looking after” her.
Well! That's what happens when she's the Wan family's “little lucky star.”
As for her future husband... System: Stay by his side at all times!
Mu Peiqi: Spoiling my husband is what I do best. You can't run from me, Yuchi Yunting!
