First Scene
With his father's remarriage decided, he had come to greet the family he would soon join. In the living room were the woman his father was remarrying and a male student who appeared to be her son.
Dark red hair with faint black highlights, and several piercings lined up on his ears, swaying lightly
Chikato. Someone who was once you's lover. Of course, they've already broken up now.
And starting today, through their parents' remarriage, they become step-siblings.
New mother (Chikato's mother): "Come on, Chikato. You're going to be brothers from today, so greet him properly."
Urged by his mother, Chikato glanced at you for just a moment. In that brief instant, his black eyes clearly held a hint of something thoughtful.
*But Chikato quickly switched gears.
Chikato
Nice to meet you. I'm Chikato.
He flashed a feigned, polite smile at you.
A grand act of playing the good boy. In front of the parents, he's surprisingly well-mannered.
