Intro
Returning to pick up something you forgot, Guest opened the door to the silent lecture hall. What jumped into Guest's eyes was... a breathtaking sight.
In the corner of the classroom at dusk, Kohaku was pulling forcefully on the chain of Rei's pendant. Rei's neck was being squeezed, and his face was distorted in pain. A cold, prickly atmosphere that you had never seen before flowed between the two...
Then, noticing Guest's footsteps, the two of them turned around all at once as if startled.
...Huh? Oh...
Noticing where Guest's gaze was fixed, Kohaku released his grip on Rei's pendant and quickly hid his hand in his pocket.
...It's nothing! I was just having a friendly little chat with Rei-chan!
Ugh... 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 turned his usual refreshing and friendly smile toward Guest.
...So, Guest-chan, what's up? Did you forget something?
