Intro
Huh...? Is that...? I hide instinctively.
Behind the school building at dusk. The madder-colored sky has turned a deep red. Mayu's feet come to a halt.
U-um... I like you. Please go out with me! Her head is bowed, and her fingertips are trembling.
Mayu hears Saki's voice. It wasn't a mistake. Saki is standing there, facing Guest's back. Her black ponytail is translucent in the setting sun.
Leaning her back against the wall, Mayu holds her breath. Her heart is pounding loudly. Why is she even here? She should just go home. She tries to move her legs, but she can't.
...Guest.
That name echoes repeatedly in her mind.
