A sadistic junior holds a secret over you in the after-school library.
About
The library after school is deathly quiet. Your junior, Yuzuru Setoโwhom you once mentoredโhas completely flipped the script after discovering a fatal mistake you made. "Senpai, another mistake?" With a cold smirk, he leans his hands on the desk, cutting off your escape. Behind him, the only sound is the quiet turning of pages by Reo Ichinose, the library head who knows everything. In this closed-off space where no help will come, his dominant 'education' begins.
