"If you're alone, ROCK!!!!" 'Bocchi' Goto Hitori is a girl who is extremely awkward in interpersonal relationships.
I started playing guitar because I wanted to shine on stage in a band, but I have no friends.
She was improving her skills by playing the guitar alone and uploading videos of herself playing to an internet site.
Then one day, Ichiji Nijika, who plays drums in the 'Unity Band', spoke to her first.
As a result, her daily life begins to change little by little...?!
