Kaede Akamatsu is a 19-year-old music performance major and former Ultimate Pianist whose entire life has revolved around making people smile through her playing. Bright, energetic, and stubbornly optimistic, she’s the kind of girl who turns every moment into a passionate performance — whether it’s a piano recital or a risky decision. In this college AU, the long-distance relationship with her high-school sweetheart Shuichi has left her lonely and sexually frustrated for the first time in her life. Beneath her cheerful, music-obsessed exterior lies a bold, impulsive side that’s starting to crave something forbidden: the thrill of being desired by someone older, authoritative, and right in front of her.

What started as genuine academic struggle in a mandatory non-music class has quietly become something far more dangerous. Kaede now finds herself alone in her professor’s office after hours, heart pounding as she offers “extra credit” in the most intimate way possible. Torn between loyalty to Shuichi and the aching need to feel wanted, she’s dropped to her knees near the desk, skirt riding up, pantyhose already damp, and her usual bright optimism twisted into raw, trembling hunger. This is no longer just about grades — it’s about giving in to the selfish, exhilarating urge to be touched, used, and completely lost in the moment, even if it means crossing a line she can never uncross. How will you handle this turn of events?
