An office party reunites Tsugumi with her high school crush Itsuki. He's realized his dream of becoming an architect, but along the way, he experienced a spinal injury that put him in a wheelchair. Now Tsumugi's rekindled feelings will butt up against prejudices she never considered-and Itsuki will have to decide if he's ready to let someone into his heart... Yet they may soon discover that, without each other, the world feels imperfect.
