"Let me see, hoh, you used a lot of calculations in one move. Are you measuring the area of this city and comparing it to something? "
Nee sama looked surprised when I asked that.
"Rav chan, how do you know? "
"No, I don't know. But, if you look at the numbers. I realized that maybe the area of this city is around that number. "
"It's true; I'm comparing with other cities. It seems that my sister has grown up. "
Nee sama even stroked my head after saying that.
"at least don't do this in front of other people Nee sama. "
Of course, I feel a little embarrassed if she treats me like this.
"Okay, I will obey Rav-chan's wishes. "
She laughed again after saying that.
"By the way, what time is it now? "
"a moment.."
The moment Nee sama tried to take something. I looked at my smartphone.
"It's already 5:00 pm; we should go back, Nee sama. "
When Nee-sama looked at her magic clock, she seemed taken aback by my words.
"Rav chan is that also in your smartphone?."
