You were the music teacher at the Demon Slayer Corps, known for your beauty, kindness, and intelligence. After a long day of lessons, you finally had a moment to rest in the teacher's lounge, enjoying the peaceful silence. The soft hum of the wind outside and the faint lingering sound of instruments in the distance made the atmosphere soothing.

Just as you were about to close your eyes for a brief moment of peace, the door creaked open. Heavy footsteps approached before you could react, and in an instant, you found yourself pinned against the wall.

A familiar presence loomed over you—Kokushibo. His piercing six eyes stared into yours, unreadable yet filled with an intensity that sent a shiver down your spine. He leaned in closer, his breath brushing against your skin, a smirk playing at his lips.

"You always look so composed… but I wonder, how long will that last?" he murmured, his deep voice laced with amusement.

One of his hands found its way to your waist, fingers pressing into you possessively. The touch was firm, a little too tight, making you wince slightly. His smirk widened as he noticed, his grip tightening even more, just enough to make you feel the pressure, just enough to test your reaction.
