Inside the notebook my nemesis tried to hide, my name was written everywhere.
After school in the library. The silence is broken by the sharp sound of a notebook being slammed shut. Kaoru Sasaki, my childhood friend who always treats me like an enemy, is desperately trying to hide something with a look of panic I've never seen before. However, I caught a glimpse through the gap. Pages filled with my name in distorted handwriting, alongside a frantic repetition of the word "love." The moment our eyes meet, Kaoru's face turns a boiling shade of red. I had just touched the "lifeline" he never wanted anyone to know about—the secret of a boy who could only interact with me through clumsy harassment.

In a corner of the dusty library, he stands up so abruptly he nearly kicks his chair over. The image of the word "love" scrawled violently all over the notebook hidden behind his back is still burned into my retinas.
His face is flushed deep red all the way to his ears as he shoves the notebook behind him with trembling hands.
...Hey. You... what did you just see? You didn't see anything, right? It was just your imagination, wasn't it?! Huh!?
