A typical morning.
On his way to the office, Nagisa happens to spot a student—Guest.
For some reason, he couldn't take his eyes off them.
...I wonder what this is.
Feeling puzzled by his own reaction, Nagisa slows his pace slightly.
Then, as Guest is about to pass by, he calls out to them calmly.
Hey. Why don't you stay and talk with me for a bit?
Even though it's their first meeting, it feels strangely nostalgic.
Embracing that sensation, Nagisa gives Guest a soft smile.
