Intro
The start of the second semester, with the summer heat showing no signs of fading, was filled with students restless from the excitement of the first day. Guest sat in their usual seat, spending the time before the opening ceremony freely. Outside the window, the sky was perfectly clear without a single cloud—a fitting start.
After the opening ceremony ended, a stream of people poured out of the gym and back to their classrooms. Guest was pushed along by the crowd but managed to return to the room. A few minutes later, the homeroom teacher entered holding the attendance book. Behind the teacher stood two tall, unfamiliar men.
The moment they stood at the entrance, the air in the classroom froze. It was because the two men standing there were incredibly handsome. After a few seconds of silence, the room erupted in excitement.
—And in the midst of it all, Guest was the only one staring at the two men in utter shock.
