Yo-han is the son of a Christian minister. Following his father’s career, he joins the seminary without much enthusiasm, then drops out. After doing his military service as a KATUSA, he teaches at the U.S. educational center. When he is given a job teaching in America, he hastily marries in preparation for the move. He is suddenly struck blind, then begins contemplating suicide. Instead he has a religious vision and dedicates himself to the ministry, and opens a church for the blind.
