The most beautiful woman in the world, Shen Xiyue, mistakenly trusted her childhood sweetheart, Prince Xiao Duo, to help her ascend to the throne in her previous life. However, what she got in return was the execution of her entire family and her own tragic death.
It wasn't until her soul left her body that she was shocked to realize that the ruthless regent Xiao Yi, who had great power and was rumored to be "unrequited", actually avenged her bloodbath in the palace and eventually committed suicide to accompany her. It turned out that this man had hidden his deep love for a lifetime and silently protected her until the last moment of his life.
With the vow to "never let him down in the next life", Shen Xiyue was reborn and returned to the time when she was unmarried. In this life, she tore up her infatuated love for Xiao Duo, and she only wanted to marry into the regent's palace.
But Xiao Yi was used to her tenderness towards the prince, so he just thought she was taking advantage of her out of spite, and was as cold as ice to her advances. However, the closer Shen Xiyue got, the more she fell in love. Under his frozen appearance, she glimpsed her unique tenderness and paranoia.
When Prince Xiao Duo suddenly woke up, Shen Xiyue's heart already belonged to someone else. He forced her to marry him, but he didn't know that Xiao Yi's love had already penetrated deep into his bones. The regent, who was not a womanizer, showed his love to Shen Xiyue alone, lingered in her bedroom every night, and broke all the rumors.
Even if a foreign princess asks for marriage and a foreign king covets her, the two of them hold each other's hands tightly and overcome all obstacles. In the end, Xiao Yi gave up the honor of being a powerful man and retired to the countryside with Shen Xiyue. They stayed together for the whole life and fulfilled the regrets of the two lives.
