Prologue

My name is Yamagi Yugi, working in a well-known company, the parent company "Nagai" is a cola drink company that is currently popular in Tokyo.

The clock on the hand shows twelve o'clock at night, this is really overtime, because there is important data that must be sent immediately.

There are only three overtime workers here, namely me, Atsushi, and Miyamae. It seems they are serious about achieving the salary they want, meanwhile I was sentenced to overtime for being absent for two days.

"Ow, so sleepy."

This is really hard for me, especially when I'm too lazy to type on a computer screen.

"Damn it's still a miscalculation, this is bad...."

I thought the coffee would make my eyes come to my senses and get rid of this drowsiness, I stood up from the chair while allowing the others to go to the ground floor, where it was a free space to bring the coffee machine

I was on the third floor, and unfortunately the elevator was still closed and couldn't operate because it was broken so I had to go down the stairs.

"It's so dark, and scary...."

Even my voice was getting weaker due to sleepiness, I descended the stairs about five steps.

I held my head which was starting to get dizzy, even I was always yawning, a sign that I wanted to sleep soon.

"Hoahm sleepy...."

My movement began to stagger, I don't know what happened, it's just that my foot slipped and fell from a height of ten meters and fell at the bottom of the stairs, even though there were still many stairs that I had to pass, to get to the free space.

My blood gushed from my chest, until my face was no longer formed, I fell to the bottom of the stairs and died on the spot.

If I hadn't been absent at that time, it definitely wouldn't have turned out like this….
