Human loneliness experienced by a foreign girl living in a large city without a connection to anyone, she desperately tries to forge a bond with strangers by losing her key, and relies on their kindness and goodwill for its return. She uses the key as a catalyst for a connection with people and makes a gambit by offering tea, a cultural bonding ritual in South Korea to have somebody close even if it is just for a moment. The human presence, although awkward and often unpleasant is a reprieve from being alone.
