The Chen family and the Zhao family had an ancestral marriage agreement. The eldest daughter of the Chen family, Chen Jiahe, took her younger sister Chen Shixin away to marry to the Zhao family in Kyoto. Yu is married to Zhao Geyun, the only son of the Zhao family. Less than a year later, Chen Jiahe, the eldest daughter of the Chen family, suddenly died in the Zhao family while pregnant. The Zhao family unanimously announced that "the wife died of an illness during pregnancy."
Chen Shixin, the second daughter of the Chen family, has no reason to stay in the Zhao Mansion anymore. But this Chen Shixin has already had a deep love for her brother-in-law. How could Zhao Geyun have feelings for her like a wife and sister?
In the sixteenth year of Jingde, Chen Shixin left the Zhao Mansion.
Chen Shixin: When you married your sister, you were just forced by the pressure of your ancestors. What's more, I'm a little girl, how could you like me! That's it. After all, it's a place that doesn't belong to me.
Zhao Geyun: You are only over ten years old, so how do you know what love is in this world? Although I love you, how can I be selfish enough to keep you by my side? Wouldn't you blame me when you grow up? Just like your sister…
One thinks he's not worthy, but the other doesn't dare to love.
In the 22nd year of Jingde, Chen Shixin met Zhao Geyun again.
Chen Shixin: That's it! As long as I can be by your side, even if I am my sister's shadow, so what~
Zhao Geyun: Going around in circles, God allowed us to meet again. This time, I can't let you go again!
Purpose: May all secret loves finally get married
