In her previous life, Su Nian was killed in a fire deliberately set by her best friend, Jiang Yao. Reborn one day before the disaster, she gets a second chance at life. When Jiang Yao tearfully claims that her boyfriend has confiscated her identification documents, Su Nian pretends to comfort her, secretly calls the police, and immediately heads to Sanya to stay out of danger. Jiang Yao repeatedly shows up at Su Nian's home and workplace to harass her, even bringing a locksmith to force open her door. Su Nian drives her away by pretending to offer her a loan, then rents out her apartment and hires strong men to guard it. When Jiang Yao sets fire to Su Nian's family home, Su Nian has already moved her grandmother to safety, and surveillance cameras capture the entire arson. Meanwhile, Jiang Yao's mother launches a hostile takeover of Su Nian's company, but a man Su Nian previously encountered on the beach suddenly appears as the new boss and brings down the Qiu family.
