Pah Doyeon is a broke college student in a rundown apartment building, so used to the thugs hammering on her neighbor door that she barely looks up anymore. Then one night she watches them try to break in, and on impulse she hides the woman next door, Jinju, inside her own place. Jinju is older, guarded, and carrying debts Doyeon does not understand, and the longer their awkward cohabitation drags on, the harder it gets for Doyeon to name the want that keeps pulling her toward the woman across the hall.
