This drama is completely original by Shinji Nojima. In this work, Iitomo Wan Rijiang plays the role of an unemployed vagrant who has been squatting at home for 10 years since he was 18 years old and has lived with his cartoonist father Zhangji. When she squatted in her house for ten years, Zhangji's manga was cut. The editor offered him a job to paint a love story with best-selling author Kumon Ryuyan, and Kumon put forward only one condition: water as the protagonist.
