Li Yiyi is the unknown illegitimate daughter of a mining tycoon. After her mother passed away, her world completely collapsed, leaving her with endless nights and incurable insomnia.
Li Ze, the boy who was bravely rescued by Li Yiyi when she was a child, was tricked by fate and chose a path that was contrary to her inner love, and finally tried to commit suicide in despair.
A girl who couldn't sleep met a boy who wanted to commit suicide on the rooftop. The two wounded hearts found comfort in each other's warmth. From then on, love bloomed quietly in the night.
However, the road to love is never smooth. Li Ze's super controlling desire in their relationship made Li Yiyi feel uncomfortable and "chicken".
Five years later, under the arrangement of "fate", the two met again because of their children. By chance, Li Ze moved into Li Yiyi's home, and as they gradually got to know each other, they uncovered their original misunderstanding.
When Li Yiyi conducted an in-depth investigation into the truth about a mining accident and revealed a series of intricate conspiracies, she accidentally discovered a series of "abnormal" behaviors of her father. Faced with misplaced fatherly love, Li Yiyi finally opened up her heart and began to face her true feelings.
In this battle between justice and family affection, Li Ze has been protecting Yiyi at all costs, even at the cost of his life.
In the end, the truth was revealed and the misunderstanding was resolved. After experiencing the test of life and death, the two cherished each other's existence even more.
