Ji-woo, a previous mechanic for racing cars who now runs a car repair shop, has a peculiar regular client who consistently arrives after closing hours. This client is Bin, a race car driver who was once part of the same team. Since then, Bin has secretly developed feelings for Ji-woo. To charm the playful Ji-woo, she seizes any opportunity she can—asserting that she needs to "cool down" following a race—to fervently spend the night with him in his garage. Soon enough, Ji-woo finds himself anticipating Bin's visits. However, her routine of departing immediately afterward, as if it were trivial, begins to unsettle him—and a new longing awakens within him: the desire to keep her close, even if it means causing her some distress.
