Four different couples' love stories are told as they each visit a cafe in a quiet alley. Their romances are in different stages, from sweet to bitter, like the different varieties of coffee available at the cafe.

In Seoul's Seochon neighborhood, stories unfold across seasons. On an autumn day, Han-kyung, an artist, meets women while seeking love. In summer, Bo-ra finishes work at a nail salon and uses a man to attract another at her favorite bar. In winter, Ma-ri, an actor with memory loss, joins a film director's ambiguous story. Their lives intersect, weaving a tapestry of hope, desire, and reality within the same space over time.
