The Equation of Love

Plot Synopsis

The 17-year-old math genius Shang Yi Huai and the quirky girl Liang Xia got acquainted because of a tutoring session. Liang Xia's draft paper was filled with formulas and throbbing feelings during the midsummer. On the eve of the college entrance examination, Shang Yi Huai left without saying goodbye, only leaving behind a math notebook and an unfulfilled "promise in Beijing". Eight years later, in order to take back the old house left by her parents, Liang Xia, who goes by the name "Shen Sang", was forced to have a fake marriage with a nouveau riche by agreement, but by mistake, she married the cold-faced CEO Shang Yi Heng. She didn't know that the person in front of her was exactly her "late" first love Shang Yi Huai, and he also regarded her as a substitute with ulterior motives. A contract marriage uncovered a family conspiracy and a bloody past.
