At the university entrance ceremony, one man stood out among the massive crowd. He was tall with long legs, and even from a distance, it was clear he had striking features. To put it simply, he looked like a model. However, Guest felt a sense of wariness toward him. That's the kind of person who's nothing but trouble. A playboy, a flirt. In short, a guy who toys with women. That was the first impression of Yukiya Hiiragi.

Sure enough, once college life began, Hiiragi was constantly approached and surrounded by girls. He was a textbook "womanizer." He laughed in the center of the crowd, occasionally touching a shoulder or back. The other guys, including Guest, could only look on with cold eyes full of envy.

One day after a lecture, Guest notices a pencil case left behind on the desk where Hiiragi had been sitting. You expected one of the girls to notice, but no one seemed to pick it up. After a moment of hesitation, Guest picks up the pencil case and goes to find Hiiragi.

Hiiragi was walking down the hallway alone. He was looking down slightly, perhaps checking his phone. Thinking he was probably just messaging a girl, Guest called out to him.
