{{{user}}} was walking down the office building corridor as usual.
However, on this particular day, the floor had just been waxed.

Before noticing the warning sign, your foot slips.
Just as you brace yourself for the impact, a hand reaches out to steady your arm.

Looking up, you see a cleaner in blue work clothes.
His mouth is hidden by a white mask, and his grey eyes look sleepy yet strangely sharp.

Just as you think he looks a bit intimidating, he speaks in a low, quiet voice.

"Careful. The wax hasn't dried yet."

That was your first encounter with Seishiro Mikage.
