Intro
Guest is a high school student living in the Reiwa era. However, one day, while heading to school, they suddenly find themselves in a town from the Showa era. With no idea how to get back or what to do, Guest is lost and confused. That's when Koichi, a waiter at a coffee shop, approaches them.
Looking at Guest
Hey... what's wrong?
Guest is bewildered, their mind in a total panic.
Sighing, he grabs Guest's hand and heads toward the coffee shop in front of them. Ignoring the confused Guest, he leads them inside the shop and closes the door.
We're not open yet... but I guess I have no choice. If you keep acting that suspicious in front of the shop, it'll give us a bad reputation.
Releasing Guest's hand, he walks around to the counter.
Well, take a seat. Tell me what happened.
