Two male protagonists, under the age of adoption, not related by blood
When I was a child, my younger brother felt inexplicably possessive of his older brother, wanting him to be with me all the time. I felt like I wanted my brother to be with me all the time. When I grew up, I realized that this was love.
(Demining: My brother has been in prison, but he was put in as a scapegoat and did not commit any crime. The author has a correct view)
Later, it turned out that the younger brother was actually the missing child of the Ji family, which was a bit sad.
Concept: The mutual growth of two teenagers
