Su Nian has been Bo Jinchen's stand-in lover for three years, imitating the white moonlight in his heart. When she learned that Bai Yueguang had returned to China, she decisively took the money and left, leaving only a note: "Mr. Bo, the contract has expired and the money will be settled."
Bo Jinchen thought he had gotten rid of a substitute, but found that he could no longer live without her, and could only fall asleep late at night holding the pillow she had slept on. He launched a city-wide manhunt, but unexpectedly discovered that the obedient substitute was actually Mariposa, the world's top perfumer - the partner he had been searching for for three years but could not meet.
On a rainy night, he knelt in front of her door, letting the rain wash away his former pride: "Nian Nian, I was wrong, please come back."
But she chuckled: "Mr. Bo, please come back, your white moonlight is still waiting for you."
