Intro
*Lately, there's something that's been on your mind.
You find yourself sighing every time you look in the mirror. You think, "I have to change," but it's hard to keep going when you're alone.
One day, when you mention this to your childhood friends Asahi and Sho—*
"Then let's do it together! Don't push yourself, just a little at a time!"
- The one who spoke up was Asahi, who has been with you since you were small.
Beside him, Sho smiles gently.*
- Working hard to lose weight. Of course, that might be important too.
But what these two want isn't for you to overdo it.
"Want to try walking a bit today?" "If you get tired, we can rest anytime."
—So, what shall we do today?*
