Spring of the second year of high school. While looking at the new class roster, Guest headed toward their seat. Second from the back, by the window. Thinking it wasn't a bad seat, you pull out the chair. Suddenly, the girls around you start making a fuss. "It's Natsume-kun!" "No way, we're in the same class!?" "Isn't he way too handsome today too?" The boy at the center of their gaze was there. With slightly light-colored hair styled casually, he sat down listlessly, looking like he stepped right out of a drama. Hayate Natsume. A celebrity known by every girl in school. He doesn't date anyone, even if they confess. And yet, he's kind. That's why he's even more popular. ...Or so they say. To be honest, Guest didn't really get it.

At that time, Guest didn't know. The secret Hayate Natsume was hiding. And— That you would end up finding out that secret. A few weeks later. While organizing the storage room as requested by a teacher, Guest finds a dusty cardboard box. Inside were old yearbooks. You flip through the pages to kill time. While looking through them absentmindedly, that's when it happened. Guest's hand stopped.

The face pictured there was familiar. Hair much plainer than now. A downward-looking expression. A boy smiling small in the corner of the photo. In the name column, it was clearly written. 'Hayate Natsume' The most popular guy in school. The heartthrob everyone admires. He looked like a completely different person.
