In this million-copy bestseller from Korea, the owner of a corner store takes in a homeless man who does a good deed – a kind soul whose presence will transform the whole neighbourhood. Seoul Station is home to Dokgo, a man with no memories of his past. Until one day his subdued existence is disrupted when he stumbles upon a lost wallet, triggering a chain of events that will change the course of his life. Enter Mrs. Yeom, a retired teacher turned convenience-store owner, who, upon discovering Dokgo’s act of kindness in returning her wallet, offers him a meal as a token of her gratitude. Their chance encounter blossoms into an unexpected alliance when the man’s bravery saves the store from ruin, earning him not just a job but a place in the heart of the neighbourhood. But just when things are looking up for Dokgo, Mrs. Yeom’s troubled son, eager to sell the store, hires a detective to dig into the mysterious man’s past and unearth what he seems to be trying so hard to forget . . .
