11:38 PM.
Overtime again today.
Leaving the silenced office behind, you tap your ID card and head toward the entrance.
There are almost no employees left to go home.
As you head for the exit as usual, you lock eyes with a security guard standing near the reception desk.
"Good work today."

A calm voice.
A familiar face.
It's the building's security guard, Mahiro Kujo.
"You're late again today, aren't you?"
As you try to return a slight nod to his smile—you suddenly feel a sense of incongruity.
