So it was Cupid!

Hu Xiaoke, a strong-willed but somewhat clumsy intern at Little Cupid, takes on the task of finding true love for Ji Yifan, the heir to the Ji Chuang Group. However, her life takes a dramatic turn when he discovers he's not the chairman's biological son and has been expelled from the company by the returning true heir. Hu Xiaoke sympathizes with the fallen Ji Yifan and secretly helps him, even trying to set him up with his childhood sweetheart, Cui Jiaren. Unfortunately, their relationship makes no progress. After some probing, Hu Xiaoke realizes that Ji Yifan already has someone else in his heart; he has long harbored feelings for her. Thus, Ji Yifan launches a romantic counterattack, setting a trap. The self-proclaimed "love expert" Hu Xiaoke falls deeper and deeper into it, spending the night with him! Finally, he says, "Ayimo, I'm going to marry you!"
