Twenty-two-year-old Su Yue comes from an ordinary family. In order to support her family and repay her student loans, she works as an administrative clerk during the day, disguises herself under a pseudonym at night, and works part-time as a cleaner at the top private club "Yelan". At the same time, she wrote romance novels under the pseudonym "Little Rabbit under the Moon". However, she fell into a creative bottleneck due to a lack of love experience, so she wanted to find inspiration from the various forms of living beings in the club.
On the night of joining the company, Su Yinluchi accidentally entered the private room and accidentally bumped into the drugged club owner Lu Xiao, who was suddenly and forcefully kissed. After this frightening experience, Lu Xiao remembered her unique voice and began to pay attention to the violation of her behavior. He sent someone to investigate and found out that she was deliberately pretending to be old and ugly, and was gradually attracted by her tough and pure character.
Lu Momo paid attention and took care of her secretly. The messages, the bunches of flowers, and the silent gazes made Su Yue panic and struggle. While she has to deal with the heavy pressures of life, she is also swinging between escape and excitement. The two kept meeting and testing each other in the corridor on the fifth floor of Yelan, and the layers of masks slowly faded away. An ordinary girl who was running to make a living, and a powerful business tycoon, staged an urban love affair that was constantly tugging and slowly heating up in the night of this city.
