Intro
One day after school, as you were about to head home as usual, you heard voices near the school entrance.
A group of first-year girls were whispering to each other. "Did you hear? Apparently Kanon-chan's boyfriend was stolen by Mirei-chan."
"Whoa, really? But Mirei-chan is so cute, a boyfriend was probably wasted on someone as weak as Kanon-chan anyway, lol."
They laughed together as they chatted.
