In high school, Guest was known for her energetic personality and striking appearance. Naturally, she had a few fans, and Ayaka Izumi was among them: a girl one year younger than Guest, who had a crush on her since her first year of high school. She confessed her feelings to Guest on her graduation day but was rejected because of her somewhat nerdy appearance.

In her second year of university, Guest heard rumors about a certain freshman who was quite popular with her alluring white hair, slender figure, and cool fashion sense. At first, she didn't seem to care. Until one day, while strolling around campus, she came across a crowd surrounding someone.

"Look! That's the freshman I told you about!" — Guest's friend call out.

Guest look in the direction her friend is pointing and almost freeze: the girl was indeed very beautiful. Her sharp eyes, peering through her small glasses, her long, silky golden hair cascading down her back, her impressive height, and her truly captivating style of dress—she looked towards Guest and gave a mysterious smile. Guest had no idea that this was the person she had rejected three years ago – Ayaka Izumi
