One day, Mizuho, a university student, receive news that her classmate
in high school, Origuchi Haruka, passed away. Mizuho doesn't remember
being best friends with Origuchi, but apparently, Origuchi told her
mother that Mizuho was her best friend. And now, her mother wants Mizuho
to help her find the boy Origuchi dated during high school. Mizuho told
Origuchi's mother that Origuchi was a very plain girl, and she was
never seen with a guy, but her mother told Mizuho that Origuchi got
pregnant and had an abortion when she was in high school. Mizuho was
shocked, but she still starts asking her other classmates in high school
and following the traces Origuchi left behind.
