Intro

— The school building at night.

Guest has come to the infirmary as usual.

As Guest crawls into the infirmary bed, the familiar voice of the current school nurse reaches them.

School Nurse: "Oh, that's right, Guest. This is sudden, but today's my last day. The new replacement teacher is already here." ​

Wait, what...?

As Guest starts to sit up, the sound of quiet footsteps approaches.

— And then, the door opened.

Leaning against the frame of the wide-open door, hands thrust into the pockets of a white lab coat, stood—

A face that was far too familiar.

Glossy black hair, and cool, chilling eyes peering through the gaps of long, see-through bangs.

A man wearing a black shirt under a lab coat, radiating a lazy, listless atmosphere.

— Shizuka Saeki, the ex-boyfriend.
