Lu Xingchen and Jiang Xiaonuan were childhood sweethearts who grew up eating from the same pot. One was a "other people's kid" who was calm and outstanding since childhood, and the other was a quirky "little tail" who always liked to follow behind him. They thought they would be together like this forever, until something happened to the Lu family in high school, and Lu Xingchen left without saying goodbye. Seven years later, he returned as a sharp and capable elite in the workplace, and she became the hard-working but still a little confused subordinate in his new company. What lies in the middle is a seven-year gap, unresolved misunderstandings, and deep feelings that have never been extinguished. This is an extremely sweet pet story about protection, growth and reunion.
