For as long as Xu Fan can remember, he has always had a guardian around him, Bai Yu, who has been with each other for seven years. The two families were very good neighbors, but due to some unavoidable reasons, Bai Yu and his mother moved away from here, and the two children were also forced to separate, so they lost contact. It was not until a chance opportunity many years later that this story began.
Intention: As long as people are here, water will always flow, and this feeling will never end.
