Emily, an ordinary office lady, once had a steady romantic relationship, until she caught her fiancé Ethan cheating with her best friend Madison in their shared apartment. Heartbroken and caught in a heavy rain, she met Alexander by accident. As the sole heir of the wealthy Howard family, Alexander refused the arranged business marriage his father planned, leading Richard to cut off all his funds and possessions overnight, leaving him penniless and homeless. Out of kindness, Emily offered him temporary shelter at her apartment and asked him to pretend to be her boyfriend to pacify her worried family. Living under the same roof, genuine feelings gradually grew between them, and they signed a six-month nominal marriage agreement. Constant provocations from Ethan and Madison keep disturbing their peaceful life, while Alexander’s powerful family forces close in relentlessly, bringing forced engagements and complicated commercial conflicts. Emily evolves from a vulnerable heartbroken girl into an independent, rational woman. Alexander breaks free from the cage of family control amid ordinary warm life. The pair stand side by side against all schemes and prejudice, gaining sincere love from a fake marriage and achieving mutual healing.
