Modern corporate-slave besties Lin Niansheng and Su Wanqing unexpectedly both transmigrate into a period novel, waking up as the neglected sisters-in-law of the Fu family. The original owners: one was timid and tormented by her mother-in-law, the other had a marriage in name only. Dropping their old attitudes, the two team up to fiercely stand up against their difficult mother-in-law and the scheming green-tea female supporting character, resolving internal household conflicts while pursuing handmade entrepreneurship and building their careers. Feelings gradually blossom as they interact with the two Fu brothers. But with the secret of transmigration hanging over their heads, can they truly stand firm in this world?
