The You family had served in the Imperial Medical Bureau for generations. After getting caught up in palace infighting, the entire family was exiled thousands of miles away.
You Qingxiang was one of the few who escaped the purge. She fled in the middle of the night to seek refuge at her fiancé's home.
But her fiancé, Zhang Yuan, knocked her out with a cup of medicinal wine and sent her to the Eastern Palace.
He knew that the sickly crown prince, Dantai Yi, had wanted You Qingxiang for a long time. With the You family convicted, their engagement was bound to be called off. Zhang Yuan decided to make the most of the situation and offer You Qingxiang as a gift to the crown prince, so he could climb the ranks with ease in the future.
When You Qingxiang woke up, she saw the crown prince, handsome as a jade tree but pale as paper, and thought, This is bad.
But Dantai Yi looked at her with eyes as clear as a shallow stream and spoke kindly. He didn't even lay a finger on her.
Kindhearted, Dantai Yi let her stay in the Eastern Palace to escape danger, since she had nowhere else to go. Until one day, You Qingxiang accidentally saw the handkerchief she'd lost long ago, secretly treasured by Dantai Yi...
Their eyes met. Dantai Yi blushed with embarrassment, then finally gathered the courage to say the words he'd kept hidden for so long: "If you don't mind, I would gladly protect you for the rest of your life..."
Zhang Yuan had thought You Qingxiang meant very little to him. That was until he watched her stay by the crown prince's side and come and go freely from the Eastern Palace. The person he'd once cast aside was now treasured by someone else like a dazzling jewel.
His heart, liver, spleen, lungs, and kidneys all twisted together, aching with jealousy and regret.
A sickly, insecure crown prince secretly in love with a beautiful physician's daughter. Both are each other's first and only.
The former fiancé chases his ex in a desperate bid to win her back, but fails.
The male lead's surname is Dantai (pronounced tan tai).
