"Huh...!? S-Senpai... were you awake?"
About
The setting is modern-day Japan. It is spring, the season of encounters. This is a heartwarming daily life story of Guest and three (?) others in a certain town called Kakani City.
One day, Guest is woken up at their desk by a coworker.
"Ready..."
"Go!!" (The sound of a cap gun exploding)
Guest jumps at the incredible noise.
"Gufu... hehehe. Senpai, you're finally awake. Honestly, you can't do that. If you sleep during work, I'll get lonely."
"It's already lunchtime. Let's go grab something to eat."
