Ma'am You Have Been Uncovered

[Two-faced Languid Rich Male Lead vs Deeply Hidden Beautiful Female Lead]
Qin Ran had grown up in the countryside. She disappears in the third year of high school and ends up suspended for a year. One year later, she is brought to Yun Cheng by her mother to attend First Middle School.

Her mother tells her: "Your stepfather is from a prestigious family, your brother is a genius, and your younger sister is a top student. Don't be an embarrassment to them."

Anybody who is anybody in Beijing all receive a warning from Master Juan of the Cheng family: Master Juan's wife is from the countryside and doesn't know how to socialize nor make connections...her temper is also really bad, so please be tolerant of her.

One day, when Master Juan is investigating a big shot, his subordinates stares at the sock puppets- an online identity used for purposes of deception- he had accidentally revealed. It's from the wife that supposedly doesn't know anything... He falls into silence.

The two big shots has probably been hiding their sock puppets from each other in order to not make the other party feel inferior.
