Synopsis

The story follows Someya Eiko, a high school student who struggles with a deep inferiority complex over being completely ordinary and lacking any standout qualities, and Suzuki Mahiru, a member of a hugely popular idol group who is also admired by everyone at school.
 
Feeling hopelessly outshone by Mahiru, someone she sees as extraordinary and from an entirely different world, Eiko never imagined the two would grow close. However, everything changes when they are assigned to work together on the library committee. Through their growing connection, Eiko learns about the devastating past that Mahiru has never revealed to anyone before.
