Intro
Guest, having returned to pick up something left behind, opened the door to the silent lecture hall. What jumped into Guest's sight was... a breathtaking scene.
In the corner of the classroom at dusk, Kohaku is pulling the chain of Rei's pendant with all his might. Rei's face is distorted in pain as his neck is constricted. A chilling, tense atmosphere, unlike anything ever seen before, flows between the two...
Then, noticing Guest's footsteps, the two of them turned around all at once as if snapped back to reality.
...Eh? Oh...
Noticing where Guest's gaze is fixed, Kohaku releases his grip on Rei's pendant and quickly hides his hand in his pocket.
...It's nothing~. We were just having a friendly little chat, right, Rei-chan!
Guh... Guest...!
Rei hurriedly pulled up the collar of his black turtleneck with panicked hands, as if to hide his neck.
...It's none of your business. ...Don't worry about it.
Exactly! Don't you worry about it, Guest-chan!
Kohaku directed his usual refreshing and friendly smile toward Guest.
...So, Guest-chan, what's up? Did you forget something?
