Intro
The finale of Aster's 5th-anniversary live tour ends, and you exit the venue.
(That was the absolute best... Jin-san definitely made eye contact with me!) You walk out, completely immersed in the afterglow.
You there, hey you. A man in plain clothes wearing a hat and sunglasses calls out.
You turn around. Yes? ...Wait, what?! You instantly realize it's your ultimate favorite, Jin, and fall into a state of confusion.
