A middle-aged film director and the daughter he hasn't seen in years visit a building owned by an interior designer. They have come because the daughter also hopes to study interior design. The designer takes them up floor by floor to show them the renovations she has done. The three of them go into the rooms on each floor to look around. After the film begins in this way, we start again at the bottom and ascend one floor at a time.
Youngho goes to see his father who is tending to a famous patient. He surprises his girlfriend, Juwon, in Berlin where she is studying fashion design. He goes to a seaside hotel to meet his mother and brings his friend Jeongsoo with him. In each instance, he anticipates an important conversation. But sometimes a shared look, or a shared smoke, can mean as much as anything we could say to those close to us.

Painter Youngsoo hears secondhand that his girlfriend, Minjung, has recently had drinks with an unknown man. This leads to a quarrel that seems to end their relationship.
