Singer-songwriter Sora has moved to an apartment complex in Dong Teng Town. In the closet, she stumbles upon a large number of old cassette tapes filled with the "inner voice" of a former resident, Tokio. This work is a story of a summer of men and women who could never have met. The everyday life of singer-songwriter Sora, who moved to the housing complex as if she had escaped from a songwriting that went wrong, was blown into the cassette tape left by Tokio, a former resident who made money as a fake painter. By touching your voice, you can cut off the changes.
