Reina is currently in her last year of high school; but had recently changed schools due to severe ableist bullying, and hopes to finish it with a clean slate. After a few days in the new year she is introduced to her volunteer assistant, a kind and upstanding classmate named Mizuki.
During the rest of the first semester they bond over the hardships of school life and become close friends with something more sprouting underneath, but not without conflict brewing in the horizon. Will they face their problems hand-in-hand, or lose their grasp on that which binds them together?
