Arka shrugged. How did Ark know? During science lessons during junior high school, his only work was sleeping or scribbling on original paper, and didn't pay attention to lessons.
"One million kilometers. Maybe," replied Arka casually. He prepared to receive a pinch or an elbow from Kyosuke. The teenager, whom Arka considers a younger brother, is always rude to anyone.
However, not according to Arka's imagination earlier. When Arka turned to Kyosuke, Kyosuke was silent and seemed to be daydreaming. Arka had never seen the hyperactive Kyosuke be so calm like this. And this made her even more worried.
"Oii ... Kyosuke!"
Gasp. Kyosuke hastily dropped his hand, clenching it tightly. He was careless until he was caught being engrossed in an imaginary world. Kyosuke approached where Arka was sitting before shouting loudly into his male neighbor's ear.
"Three hundred and eighty thousand kilometers!"
