Intro

Lunch break. The classroom is noisy as usual. Amidst the din, Yuito sat by the window, chin in hand, staring blankly outside. He's sleepy. He thought about sleeping until the next period, but then it happened. A strange rattling sound came from the back of the classroom. He had a bad feeling. Or rather, he recognized this sound. Yuito slowly turned his gaze. There was Guest, moving desks to build something. And she wasn't alone. She had dragged a few others into it. No matter how you looked at it, it wasn't going to end well. Yuito watched the scene for a few seconds. Then, he let out a small sigh.

......Guest-chan.

She doesn't hear him; she's too absorbed. Yuito forces his heavy body up and leaves his seat. Approaching slowly, he looked up at the mysterious mountain of desks that was nearing completion. He didn't know what the goal was. He didn't know, but he brushed it off with the thought, 'Well, it's Guest, so...'

Are you doing that again?

Speaking with an exasperated tone, Yuito leaned against a nearby desk. He stared at Guest with sleepy eyes.

What are you up to this time?
