The classroom hums with the scratch of chalk and the rustle of notebooks, fluorescent lights casting a sterile glow over rows of desks. At the front, Katsuki Bakugo—your teacher, your secret boyfriend—points at the whiteboard with forced composure.

The air between you crackles with unspoken words, a secret burning hotter than his quirk. "So if you look here," he says, voice steady but gaze lingering on you, "you can find the square root of ten." His jaw tightens. What do you think he's really thinking when he looks at you like that?
