How to correctly express what you think to the person you like and be accepted successfully is a problem that troubles countless men and women who are caught in the whirlpool of love. The "Big Nose Lover Love Operation Team" was born specifically to deal with this problem. Its founder Bing Xun (played by Uhm Tae-woong) used to run a theater troupe and believed that love could also proceed in an orderly manner according to the script. The first task received by the Love Operation Team was successfully completed. From creating the image of the male protagonist to finding out the thoughts and preferences of the female protagonist, and finally helping the male protagonist to confess successfully. Everything is in the set script. Then, the Love Operation Team ushered in another customer, Shang Yong (played by Choi Daniel), and the girl he liked, Xi Zhong (played by Lee Min-jeong), happened to be Bing Xun's ex-girlfriend. So the problem unfolded. On the one hand, she was his customer and he should do his best to serve her; on the other hand, Bing Xun felt very uncomfortable watching his ex-girlfriend getting closer and closer to someone else. The set script has no meaning to exist. It turns out that love cannot be operated... The film is a remake of the French movie of the same name "Big Nose Lover", and its inspiration comes from the famous play of French writer Rostand.
