The author says in the notes that Hanbit used to unconditionally sacrifice himself for other and learned to distance himself. He moved away, and with that he also moved on, and eventually started a new life with his wife. At least we can be assured he's happy too now :)
As I read this I had one major question, what about Hanbit? Hanbit literally had people dying and wanting to die all around him, I know he couldn't have been okay and I kind of wanted to see things from his perspective. Otherwise, the manga was really good and, for the most part, relatable.
