During the struggle for the throne, heir apparent Xie Yubai is gravely wounded and ends up in Qinghe Town. The town's Liu family takes him in, but his injuries are too severe for him to leave. With no choice but to lie low, he pretends to have lost his memory.
Liu Yingying is the legitimate daughter of the Liu family. Beautiful as she is, she is also an idiot, with the mind of a seven-year-old child. The moment she sees Xie Yubai, she takes a liking to him and follows him around all day.
Seeing this, Master Liu demands repayment for saving Xie Yubai's life, making him wait on Liu Yingying. If, over time, he grows even a little fond of her, the two of them can marry.
Xie Yubai naturally refuses, but gravely wounded and dependent on the family for shelter, he can only pretend to be delighted.
In truth, he thinks Liu Yingying is foolish and stupid, and he finds her unbearable.
Later, once he has recovered, he rides away without looking back. On the day he leaves, Liu Yingying runs after him with all her strength, but he never turns around to look at her.
She waits at the town gate for half a month, but her Xie Lang never comes back.
After returning to the capital, Xie Yubai once again becomes the refined and elegant heir apparent. His support in helping the new emperor ascend the throne brings him a smooth official career and an even more prestigious position. Countless noblewomen in the capital wish to marry him.
No one knows that the exalted heir apparent Xie once tried to win the favor of a little fool just to stay alive. His story with Liu Yingying is buried forever beneath the dust.
But every now and then, he thinks of her, and of those humiliating days.
Later, he learns that the little fool has regained her wits and is preparing to marry a young gentleman.
That day, Xie Yubai sits quietly for a long time, but in the end he cannot hold back. He races back to see her.
He was wrong. He truly loves her, and he is willing to make her his wife.
After Xie Lang left, Liu Yingying refused to eat or drink and fell gravely ill. After her illness, she regained her wits. It turned out to be a blessing in disguise.
Many more young gentlemen come to ask for her hand, and she chooses one of them to marry. But on her wedding day, she sees the Xie Lang who once abandoned her.
No matter how earnestly he swears by the heavens, she will never give him another look.
Her heart is hard as iron. She will never turn back.
She does not love him, and never will.
Xie Yubai's life goes smoothly in every way, except in matters of love, where he suffers in vain. He makes every effort to win her back, but the only thing he gets is heartache.
From then on, night after night, he regrets riding away from Qinghe Town that day without looking back.
If only he had turned around, even just once, Liu Yingying would not have treated him so coldly.
But there are no ifs in this world.
