The episode opens with Ahn-chae preparing a pizza. In a narration, Ahn-chae describes her pleasure of doing her job as a waitress at Pizza Hut. Back home, she spotted some photos featuring Young-min with Yujin. Yujin visited Young-min's home to work on a school project on linguistics. Fengguan asked for reasons Ahn-chae absentee. In the hostel, Yujin shared her experiences about Young-min with Ahn-chae. Ahn-chae thought to herself for a while, before she suggested to dust the room. Yujin offered her help and Ahn-chae declined it. Yujin reported that she had lost her report, and asked Ahn-chae whether she had accidentally threw it away.

Meanwhile, Renyu ran up to Ahn-chae as she was walking. Renyu talked about the content of his report, and suggested Ahn-chae to play tennis with him in the tennis court. The duo played together. At a point, Renyu was seen teaching Ahn-chae the correct techniques for hitting a ball. On the walkway at the top, Hee-ju saw Ahn-chae's attitude towards Renyu and left her friends for home.
