This is a love story triggered by a mobile phone love letter.

In Shanghai, a major oriental metropolis, Lu Yunfei, who has returned from studying in the US, decides to develop in the advertising industry. In the more than a year prior to this, he had been constantly missing his lover Su Fei, who broke up with him for no apparent reason. Calls were unanswered and text messages ignored, leaving Lu Yunfei with an unresolved heartache about the reasons behind it all.

While continuously sending sorrowful texts expressing his longing, one day these messages were unexpectedly received by Mu Beibei, who lives in a small town in Yunnan. She had acquired a recycled phone number after its previous owner (Lu Yunfei's ex) let it expire. Moved by the sincerity and persistence of the sender, she began exchanging messages under the online alias "Red Bean Sister." Thus, two close female friends who have never met face-to-face, fatefully connected through their phones—first separated by thousands of miles, then later brought close together. Despite their proximity and shared experiences of reunion and separation, neither realized that the other was the cherished confidant they knew online. After enduring countless emotional twists and turns, the Cinderella-like love story eventually blooms as per their agreement.
