After dating for seven years, Jiang Yao waited bitterly for her fiancé Pu Yubai in vain when her grandmother passed away, but he diverted his car because of his junior sister Ruan Nanzhi; the new house and wedding were everywhere overstepped by Ruan Nanzhi, and she was diagnosed with terminal gastric cancer, finally dying of a dead heart and walking away. Pu Yubai later realized that the person who risked her life to save him in the fire back then was Jiang Yao, and Ruan Nanzhi had lied to him for seven years, searching everywhere after waking up to the truth. When they reunited, Jiang Yao had already chosen to let go, and finally passed away from cancer recurrence, leaving only the dying wish, "Next life, change you to love me first."
