It's so Sweet That Childhood Sweethearts Have Sympathy for Each Other and Cherish Each Other.

I am Qian Yaoyao, the most unpopular daughter in the prime minister's house. My biological father favors concubines and turns a blind eye to me. Even a servant in the house can bully me at will. But there is also a proton Su Zhao sent from Pingguo in the Prime Minister's Mansion! His life is no better than mine, or even worse, but it makes me feel a little more balanced. Maybe it's because we share the same problem, he is my only friend in the Prime Minister's Mansion. There's nothing wrong with him except that he's cold-tempered and doesn't like to talk to me, but I just love to pester him. At least that way it makes me feel like I'm not alone. Until one day, people from Pingguo came to pick him up.
