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.
