Mu Nianyi is the only daughter of a minister. Plain-looking but exceptionally gifted, she finds herself shunned, and her blind dates never go well.
Her friend's entire family is executed, her friend is forced to marry an abusive man, and another friend is separated from the person she loves.
Mu Nianyi has only two hands and can't save them all.
When she opens her eyes again, the truth about her birth comes to light. She is the elder of a pair of twins born to the Grand Princess. Because of a ridiculous prophecy that twins were an ill omen, she was sent to the minister's household for safety.
Now the Grand Princess wants her to fake her death and return to the royal city, where she must impersonate her twin sister.
She is perfectly willing to marry the man she loves while posing as her sister, but he strikes her so hard that she coughs up blood. His heart belongs only to Mu Nianyi, and there's no room in it for anyone else.
Mu Nianyi: ???
