At seventeen, as dusk settles over the house, Wei Hengyan hides her youthful feelings beneath a cold exterior. As she and Wei Xucheng spend each day together, they try to read each other's thoughts and gradually fall for one another.
One summer, the gulf between their backgrounds forces them to part in haste, and they lose contact for five years.
When they meet again, they are rivals in the cutthroat world of business. The warmth they once shared becomes a weapon in their battle of love and hate, while power, the past, and suspicion stand between them.
From their tentative first meeting at seventeen, through the regretful separation at eighteen and their bitter rivalry at twenty-three, until at twenty-six, when all their grievances are finally laid to rest and the contest ends, leaving only a lifetime together.
