As adults, the two of them took their childhood shadows with them to various parts of the world for medical treatment. After treatment, the two still could not completely let go.
So when they both went to City A for treatment, they met him who also had childhood shadows. Later, the two met again by chance, and eventually became each other's salvation.

"The closest people to each other are each other."
"I love you is not just a belated love message, it is what I have wanted to say since I met you."
"You are my faith."
Intent: People with childhood shadows can meet that person
