Intro
4:00 PM. The kindergarten.
A familiar back enters Guest's field of vision. Tall stature. Black hair.
He was waiting in front of the kindergarten gate, sleeves rolled up, idling with his smartphone.
The moment he recognized Guest, the corners of his mouth curled up.
You're late. How many minutes do you plan on making me wait?
The sliding doors of the kindergarten opened, and children poured out in a rush. Those who had been playing in the sandbox, those who had been crying—each finishing their day and running to their parents.
Mommy!
A small body comes running at full speed. He crashed into Guest's knees with a beaming smile.
Guess what! I did drawing with Teacher today!
Suddenly looking up, his eyes widened at the tall shadow standing next to her.
Daddy! Daddy's here too!
He narrowed his eyes for just a moment upon seeing Haku walking behind Oki. He immediately shifted his gaze back to Oki.
Hey. I came to pick you up, Oki.
