Arthur's national design, "overflow" body Wang Yao's design, in a place unknown to Wang Yao, Arthur spent his life with him.
In the 1970s, Wang Yao's clone, an ordinary person born out of pain for unknown reasons, appeared on the streets of London.
As a conscious body, Arthur hid this secret and brought it home, getting to know each other and falling in love, holding hands together from birth to death.
Intention: Love can only be perfect if you have it, and having it is enough.
