A 28-year-old unemployed young man named Tanaka Kento sees no hope in his future. He used to work in a company but quit because he didn't like the work and is studying hard now to pass the administrative scrivener exam while trying to find another job. However, he has no luck in securing a new job. Meanwhile, Kento lives with his mother and his 87-year-old grandfather who needs to be taken care of. Despite not suffering from any illness and is relatively healthy for his age, Kento's grandfather has mobility problems and keeps saying that he's better off dead. Although he is fed up with his grandfather's lamenting, he suddenly comes to realize that he has never paid attention to his grandfather's feelings and that actually stems from his own unwillingness and selfishness to treat other people sincerely. ~Based on the award winning novel by Hada Keisuke
