Xia Qingying is a simple girl. Her only dream is to fly with Qi Xiaobai, who is the same age as herself but a genius, and Amu, who grew up together and is 7 years older than herself.
But... When Qi Xiaobai, whom he hadn't seen for many years, appeared in front of him, and Amu, who had been by his side all the time, went on a business trip to France, everything began to change.
Love? Friendship? Family affection? Haha... It turns out that it never belonged to me.
