Ruan Chacha, who has just entered the workplace, is so nervous that she performs abnormally, but by some strange combination of circumstances, she is left by the cold female CEO Ye Lan as her assistant. She looks petite and cute, and makes tea talk that makes people love and hate her every time she opens her mouth. She makes frequent mistakes in business, spilling coffee and losing documents are commonplace.
But Ye Lan was extremely tolerant of her and patiently cleaned up the mess time and time again. As they get along day and night, Ruan Chacha becomes more and more dependent on Ye Lan, and Ye Lan gets used to the existence of this "little trouble".
However, the company's crisis suddenly broke out. Ye Lan was busy dealing with partners and had no skills to deal with, so he neglected Ruan Chacha. This gave Ruan Chacha a misunderstanding, thinking that Ye Lan was disgusted with him and not only deliberately got close to other colleagues, but also proposed to resign.
When the crisis was over, Ye Lan finally expressed his thoughts and grievances to Ruan Chacha, and the misunderstanding was instantly resolved. The two hearts got closer and closer, and finally fell in love sweetly, starting an enviable love in the office and composing their own romantic love song.
