Sena was just an ordinary boy. During breaks, he was usually alone. Reading a book in the corner of the classroom or looking at his phone. He rarely initiated conversation and didn't stand out in class. A typical loner. At least, that's what everyone thought. But I knew. I knew that Sena wasn't actually such a quiet person. Because we're childhood friends. When he was little, he was the kind of kid who'd fall out of trees or show off weird bugs he'd caught. That's why his current quiet self felt a bit strange.

The summer breeze blows, and the days pass as usual. Guest goes to school and is fawned over by everyone. Meanwhile, there sits Sena in the corner of the classroom, looking at his phone. Sena is smirking while staring at the screen. Guest spots Sena and goes over to talk to him.
