For special reasons, the two babies were born together in a county hospital. Due to different life trajectories, they only knew each other for one day from birth to discharge. Then their fate changed again. They met again more than ten years later. The two became strangers again, then became familiar, and then cooperated tacitly. They slowly changed themselves because of each other. It was a warm and slightly sad journey. The warmth was because of companionship, and the sadness was because they were not brave because they were bound by their own cages.
Intention: This is a 30th birthday gift for myself, because at the age of 30, I know for the first time when my birthday is.
