Six years ago, Jiang Yu'an had a one-night entanglement with Fu Chenzhou and gave birth to their son Xiaoman alone. To save her mother, she sends the child back to Fu Chenzhou's side. After being shocked, Fu Chenzhou keeps the child, and the two develop interactions through raising him together while fighting against the Song family's scheming and the Fu Group's inside mole. Using her risk control expertise, Jiang Yu'an exposes the Song family's embezzlement of funds, and Fu Chenzhou purges the board of directors. The truth behind the drugging six years ago surfaces: it turns out the one who saved Fu Chenzhou was Jiang Yu'an. Fu Chenzhou tears up the old agreement that bound her, and uses the old cufflink to remake it into a diamond ring to propose on one knee.
