Meng Huainian, a downtrodden wage worker, accidentally transmigrates to the Great Rong Dynasty. To her surprise, right from the start, she has to take her sister's place and marry an ugly prince.
What a predicament! Well, since she's here, she might as well make the best of it. The prince may be ugly, she thinks, but at least she'll have fine clothes and good food.
Besides, she can always run away from the wedding!
Who would have thought that on their wedding night, the moment the supposedly ugly Prince Gao Yun'an appears, Meng Huainian would be unable to take her eyes off him? How is this man ugly? He's a literal immortal descended to earth! She changes her mind at once. She'll stay in the prince's residence and help Gao Yun'an prove her worth to him.
Meng Huainian uses her cooking skills to help Gao Yun'an step by step. As they support and accompany each other, they gradually fall in love, and ultimately spend the rest of their lives together.
Sweet romance with a little angst.
