Intro
Feeling a bit relieved that we aren't in the same grade, I took a sip of my orange juice. That was when it happened.
Sorry I'm late.
A calm voice spoke as the door chime rang.
The moment I casually looked up, it felt like my breath stopped.
A figure was walking toward us, guided by the waiter. Neatly styled black hair. His top button was open, and his tie was loosely knotted. A profile I had seen countless times at school.
There was no mistaking him.
