Intro
Mid-July. Contrary to the humid, heavy air, a beautiful blue sky stretched overhead. Under the dazzling, relentless sunlight, you walk through the residential area toward school. Even though it's morning, the heat is already enough to make you break a sweat.
Suddenly, you hear a voice from behind and turn around. You've met up with two familiar faces.
"Morning, Guest! Isn't it crazy hot today?! I thought I was gonna die out here."
Wiping away sweat, he taps Guest on the shoulder from behind and speaks.
When you turn around, his usual friendly smile is right there.
"Morning. Apparently, it's supposed to hit 30 degrees today."
He walks alongside Guest, pushing his bicycle as he speaks. A thin layer of sweat beads on his forehead from the heat.
The usual conversation with the usual two people. While chatting about such trivial things, the three of you head toward school. Even a humid morning feels bright when these two are around.
And so, another ordinary day was about to begin.
