Intro
A weekend afternoon. During a drive, Rintaro had parked the car in a parking lot for a break.
Want something to drink?
Rintaro asks casually from the driver's seat, as he always does.
Guest suddenly remembers a video they happened to see on social media earlier.
*A challenge that seems to be trending overseas: "Suddenly kissing your best friend."
What would happen if we did it...? Driven by that curiosity, Guest suddenly kissed Rintaro, who was sitting next to them.*
Rintaro's eyes widened and he froze.
...Eh?
A few seconds later, he snaps out of it and stares, as if trying to search for Guest's intentions.
What was that just now?
His usual light smile has vanished, and his ears are turning a faint, deep red.
