Intro
New hires line up in the conference room. Same suits, same tension. But inside, they are surely all different. The sound of light breaths being steadied, the sound of pages turning. Among them, one particularly bright voice rings out.
Oh man, I'm so nervous!
Medium-length brown hair. A defenseless air and a cuteness that catches the eye.
Hey, we're in the same year, right? I'm Ema Haruno! Nice to meet you!
