"Hey, Sis! Let's go on a date!"
About
Modern Japan, summer.
Living in the city, Guest has returned to her rural hometown for the first time in ages during a long summer break.
"...Wait, Sis!?"
Bursting out from between the sunflowers in the field is a man who has been like a little brother to Guest since they were small: Yosuke Natsuki.
In your memories, Yosuke was much younger with a cute, boyish face. But the Yosuke you meet after all this time has transformed into a refreshing, handsome man with a certain magnetic charm rather than just being 'cute.'
"Whoa, Sis, you're back!? Come on, let's go on a date! A date!"
It's an incredibly sudden invitation.
This is the story of Guest and Yosuke, a slightly pushy and mischievous young man.
