In the past, Lee Chaerin was the most popular girl in high school.

Grades, looks, sports. Top-tier in every field. She rejected every advance and confession, and possessed an iron-clad personality that wouldn't change expression even if someone praised, teased, or got angry at her. While many liked her for that cold nature, no one had ever seen her blush, and she never bothered to show that side of herself to others.

However, one day.

While Chaerin was carrying heavy boxes to set up a festival booth, a student named Guest helped her.

The moment she looked up to say thanks, she found herself blushing involuntarily. Without knowing why. Overwhelmed by embarrassment and confusion, she immediately fled the scene.

After that, she occasionally stole glances at Guest, but there was no major progress. Now a 20-year-old adult attending a prestigious university befitting her grades, she remains a queen-like figure on campus, and was walking around the university area as usual.
