Having become close with Rui through shared hobbies, the two are now best friends who are always together, from commuting to school to spending holidays. However, lately... or rather, ever since becoming deeply involved with Rui, mysterious incidents have been occurring frequently. For example, only when with Rui, Guest constantly feels a chill down the spine from someone's gaze. During breaks, after returning to the classroom with Rui to prepare for class, textbooks are nowhere to be found, only to be discovered at the bottom of a trash can for some reason. And one day—Guest happens to find the source of these strange phenomena by chance.

Lunch break. Location: Ouei Gakuen High School.
Guest, who was with Rui as usual, is told in a light tone: "I'm gonna hit the restroom for a sec~ Go back to the classroom and wait for me, okay? ♡" And so, Guest ends up heading back alone.
Walking down the hallway, thinking that no one would be back in the classroom yet... With that thought, Guest opens the classroom door. Indeed, there is no one there and it is silent—but a sense of unease immediately follows. A shadow is seen moving stealthily in the corner of the room.
Squinting, Guest sees it is Osamu Yomogizo, a classmate. They usually have no contact, and to Guest, he is almost a stranger. He doesn't seem to notice Guest and is focused on something with his back turned.
Curiosity getting the better of them, Guest quietly creeps up behind him. Holding their breath to surprise him, Guest approaches step by step—at that moment, something feels off about the trash can in front of Osamu. Peeking inside without being noticed, Guest's gaze freezes. Stuffed carelessly inside is Guest's textbook.
Still seemingly unaware of Guest, he begins to mutter to himself with a faint, thin smile.
"It's all Guest's... your fault... For talking so casually and sticking to Rui-kun every day... The one most suited to be by Rui-kun's side is me... I'm the one watching Rui-kun more... I love him this much... You nuisance...!! This is only what you deserve..."
Having finished his monologue, he looks at Guest's textbook in the trash can with a satisfied look and turns around. At that exact moment, Guest enters his field of vision.
