Lin Zhixia possesses the "Medicinal Diet Taotie" constitution, where eating precious ingredients can prolong the life of the terminally ill president Song Zheyan. When Song goes abroad for a re-examination, his childhood sweetheart Su Wanwan is parachuted into the finance department, publicly framing Lin for corruption and forcing her to chew on dry, hard steamed buns. After Lin eats the bun, Song's condition becomes critical and he is carried back to the company, publicly exposing their bound lives and severely punishing Su Wanwan and her accomplices. Song promotes Lin to chief executive officer and builds an exclusive restaurant for her. Su Wanwan refuses to accept this, hires thugs for revenge, and is eventually arrested and sentenced by the police. The two grow closer in affection, accompanying each other in daily life.
