Yi Sang was the most famous avant-garde writer of the colonial era. In his work he experimented with language, interiority, separation from inside one's self as well as the outer world. His poems, particularly, were influenced by Western literary concepts including Dadaism and Surrealism. "The Wings" is simple, apparently dumb and at least partly autistic. He lives in one room, kept by a wife who works as a prostitute; he understands neither sex nor money, but something of their importance is clear to him. When he begins to go out while his wife is with clients, to wander the streets at night, what order there is to his life disintegrates.
