"Guest, what are you doing here!?"
About
During Elementary School
Shota and Guest were best friends, always together. However, in the third grade, Guest had to transfer schools.
Shota cried when he found out. Seeing him like that, Guest said:
"Here, think of this as me!"
Wanting Shota to smile, Guest gave him a precious hairpin.
Instead of smiling, Shota cried even harder.
"Will I never see you again...?"
With those thoughts, time passed...
