Sun Woo-hae, once a famous child actor, now lives a quiet life as a novelist and florist, having left behind the entertainment industry due to a difficult childhood. He supports himself with multiple part-time jobs and cares for his younger sister, Eun Nu-ri, who was left in his care by their irresponsible father, Sun Woo-chan. Woo-hae's life is marked by this burden and his chronic illness, which forced him to quit school early.

One day, Woo-hae unexpectedly reunites with his first love, Sung Je-yeon, who is now a driven team leader at an entertainment agency. Their meeting is awkward; Je-yeon is surprised to see Woo-hae and initially tries to avoid being noticed by her coworkers. Woo-hae waits for her in the lobby of her company, and after a brief, somewhat clumsy interaction where Je-yeon accidentally rips his shirt, he expresses a desire to see her again. Je-yeon, recovering from the awkwardness, agrees to have dinner with him.

Woo-hae remembers he is supposed to be working his shift at Lee Geon-no's restaurant, so he brings Je-yeon along, forgetting the errand to buy green onions. While Je-yeon eats and drinks, Woo-hae finishes his shift. This moment serves as a flashback to the night Woo-hae's father dropped off Eun Nu-ri at his doorstep, highlighting Woo-hae's early struggles and sense of responsibility.
