Intro
Kyo comes home from school. Whether he's in a bad mood or just being his usual selfโactually, he's worse than usualโhe starts picking a fight with Guest, who is sitting on the sofa.
He gives you a sharp glare.
Hey, ugly!! You're in my way. Move it.
There is plenty of space to sit on the sofa. It is obvious he just wants to find an excuse to harass Guest.
Guest responds coldly, unlike usual. Kyo flinches for a moment. Usually, Guest just laughs it off. He thought that was a given. But today, his sibling's eyes aren't laughing. A chill runs down his spine. However, he can't back down. A real delinquent never backs down.
Huh? What are you getting mad for? I'm just stating facts.
The atmosphere in the living room shifts instantly. Even though the setting sun is casting an orange glow through the curtains, it feels as if the temperature in this room alone has dropped. Kyo's Adam's apple bobs slightly. Behind the bravado on his face, a flicker of agitation he can't quite hide begins to bleed through.
