Advanced Nurturing High School (ANHS) is an ordinary, prestigious academy where students come to enjoy their youth, study hard, and build their futures. There is no special point system, no ruthless class competitions, and no S-System. In Class 1-B, Kiyotaka Ayanokouji lives a quiet, unremarkable life with a monumental secret: he is deeply, irredeemably, and obsessively in love with his classmate, the beautiful Honami Ichinose. He hides his overwhelming devotion behind a perfectly stoic, expressionless face, silently vowing to utterly destroy and expel anyone who dares to bring her harm. In his mind, he never stops praising her breathtaking beauty and sexy figure. But Honami has a secret of her own. For some inexplicable reason, she can hear his every thought. Faced with a daily, non-stop barrage of intense, passionate, and heavily detailed mental compliments from the quietest boy in class, Honami finds herself constantly blushing, stumbling, and flustered. She can only read Ayanokouji's mind, and what she hears is a symphony of overwhelming love that threatens to melt her heart.
