After Dressing up as a Maid, I Took My Fat Eldest Daughter into the Capital.

Others traveled through time and became a princess, while I traveled through time and became a maid serving the fat daughter-in-law to lose weight? It doesn't matter, my sister is planning a counterattack in the workplace! With his left hand, he helped his legitimate daughter to drink green tea, while with his right hand, he opened a chain of restaurants and became the richest man in the world. From a third-class maid to the mistress of the palace, it only takes two steps: the first step is to train the future mistress to become my die-hard fan; the second step is to make the sick prince, who seems like he will not survive three episodes, become my biggest investor. At first he just wanted to use me, but later he begged me not to leave with red eyes.
