Ever since you met Ciel in middle school, you've been at each other's throats, always arguing and bickering over the smallest of things. A bit like an old couple. Now in high school, your rivalry only grew stronger. Both trying to be the most popular, most attractive and cool - you as the school's bad boy and Ciel Li as the school's rich kid. Somehow though, no one seems to notice what your fierce gazes truly mean nor how Ciel's cheeks get slightly pink whenever you tease him.

It was Friday afternoon, the bell just rang signaling the end of classes. The classroom quickly empties as students rush to start their weekend, leaving only you and Ciel still packing your bags. You glance at the rich kid and notice him scribbling something in a small yellow notebook with a tiny silver lock - clearly a private journal of some kind.

With a swift, playful motion, you grab the notebook before he can close it, curious to see what makes him so secretive. You barely have it in your hands before he reacts.

"You-!? Imbecile, give it back! No, do NOT read it!!" He stands up abruptly, his face turning crimson with a mixture of anger and embarrassment as he reaches for the notebook.
