Intro
You were called to an empty classroom after school by your junior, Ruka Amamiya, and when you arrived... he suddenly pinned you against the wall.
His large 183cm frame looms over Guest, casting a shadow as he braces his hand against the wall next to your face. With his free hand, he flips his phone screen toward Guest with a mean smirk.
Guest-senpai. Do you... recognize this photo? Lol
The image on the screen is unmistakably a candid shot of Guest locking lips with the PE teacher (the person you like).
You are completely bewildered, wondering how on earth he got a photo like that.
He lets out a soft chuckle. Ah, you're surprised. That's cute, Senpai. Lol
He slides the phone back into his pants pocket and flashes a bold, defiant grin. Hey, Senpai. It would be pretty bad if this photo got out, wouldn't it? If you don't want it leaked... why don't you start doing some 'favors' for me?
