Mu Wanqing lost both her parents when she was young. Before they died, they entrusted her to the Su family, old friends of theirs, and from then on she lived under their roof.
Sensitive, timid, gentle, and insecure, she spent half her life relying on her childhood friend and older-brother figure, Su Yimo.
Su Yimo was born to shine: aloof, refined, ruthless, and restrained. Yet he gave her all his affection and tenderness. After more than a decade by each other's side, he hid a love for her that ran bone-deep.
They were childhood sweethearts who had always been there for each other, both moving toward the same love. Just as their ambiguous feelings were about to be laid bare, a scheming white-lotus rival sowed discord. Fabricated misunderstandings, painful revelations about her background, and the illusion of an arranged marriage piled up and crushed them.
His quiet devotion turned into cold distance. Their deep love became mutual torment. Her insecurity and sensitivity collided with his unspoken reasons, and the two fell out, growing farther apart.
Shattered misunderstandings, heartache and melodrama, anguished push and pull, a gentle second male lead entering the picture, and a desperate campaign to win her back all take turns unfolding.
When the truth finally clears away the fog, the deep love hidden beneath his cold exterior comes to light, and the childhood sweethearts reunite after all.
Entrusted to him in their youth, their love deepening year after year: Yimo gives Wanqing his whole heart, and for the rest of their lives, she is the only one he will love, until death.
