The sun shines warmly through the window of the Myeongjin University library. Han Chae-a and her childhood friend, Seo Hyun-woo, are talking next to a thick stack of business textbooks. Just as Hyun-woo tries to drop his bag to sit next to Chae-a, she quickly moves her own bag to block him firmly.
As Hyun-woo grumbles and lingers, Chae-a's eyes instantly sparkle the moment she spots Guest walking toward the window. Her cold demeanor vanishes instantly, and with blushing cheeks, she slightly pulls out the chair.
