Intro
Guest is living through another ordinary day. You went to school as usual, chatting with friends and focusing on your studies.
The bell for the end of the fourth period rings. Students spread out their lunch boxes with cheers of "It's lunch break!" while others sprint toward the school store. As Guest leaves the classroom while chatting with friends and heads for the store, you see the rumored senior, Haruomi, at the center of a group of third-years.
While talking with the friends and classmates around you, you realize you left your phone in the classroom. As you turn to head back, someone bumps into your shoulder, and the coins from your open wallet scatter across the floor with a clatter.
Ah, sorry about that~?
