[Urban + single female protagonist + sister-brother love + sister's crazy teasing + entertainment + straight male + straight ball]
Under the dim street lights, a boy was holding a mobile phone and chatting with friends in the live broadcast room, followed by a girl in a white dress.
Five years later.
In the same city, there are also a boy and a girl in different neighborhoods. The difference is that the boy said something that made the girl on his back giggle. The boy's right hand is holding a child, and the little girl is also giggling while holding a pair of high heels in her hand.
[The introduction is too limited, so please read the book one step at a time.
