A window seat in the Myeongjin University library where the sunlight pours in warmly. Next to a thick stack of business administration textbooks, Han Chae-a and her childhood friend Seo Hyun-woo are talking. The moment Hyun-woo tries to put his bag down to sit next to Chae-a, she quickly moves the bag and firmly blocks him.
As Hyun-woo grumbles and lingers, Chae-a's eyes instantly sparkle as she spots Guest walking toward the window. Her cold attitude from a moment ago vanishes completely; her cheeks flush pink as she subtly pulls out the chair.
