On the day Su Wanhe was born, heavy rain caused floods. Since then, he has been stigmatized as a "rain disaster star" by the whole city. No one knew that this natural disaster was actually caused by his father's greed for money to repair the embankment and secretly replaced it with inferior building materials. In order to cover up his guilt, his father blamed all the troubles on her as a newborn.
After her biological mother passed away in childbirth, Su Wanhe grew up hard under the harsh treatment of her stepmother and the bullying of her stepsisters. He has been starved of food and endured hardship all year round, doing all the menial work at home. She is humble and has never tasted the slightest warmth in the world.
Xiao Jingheng, the cold-faced Prince Jing with great military exploits, was seriously injured on the battlefield and fell into a coma. The emperor ordered a female official to be selected to celebrate his victory. In order to protect their pampered step-sister, the Su family ruthlessly forced the helpless Su Wanhe to marry her instead. They used her as a pawn to cling to the royal family and sent her to the unpredictable Prince Jing's palace.
After entering the palace, she was still looked down upon and neglected by her servants. She could only secretly eat cold food late at night and survive by being cautious. Unexpectedly, Xiao Jingheng, who had been in a coma for several months, suddenly woke up. He accidentally bumped into her embarrassed and timid appearance, and felt sympathy and pity for her.
From then on, the cold-faced prince favored her in every possible way, supported her and protected her from her shortcomings, and dispelled the coldness of her life. Xiao Jingheng investigated old cases for many years, exposed the truth about the Su family's father and daughter who had framed their own daughter and embezzled money to harm the people, and completely cleared Su Wanhe's reputation as a disaster star that had been burdened for more than ten years.
The evildoers will eventually be punished, and everyone in the Su family will suffer the consequences. The girl who was once abandoned by the whole world lost her inferiority and cowardice under the gentle protection of the prince, and transformed into the calm and transparent Princess Jing. The world finally knows that there is no disaster star in destiny, she is just Xiao Jingheng's unique lucky star from heaven. The two of them go in both directions and finally achieve a happy life.
