A famous detective in Kansai, the youngest police officer in the history of the Osaka Police Department, a young talent, and a promising young man. Surrounded by these auras, Hattori Heiji is experiencing the biggest crisis in his life. Under a series of turbulence and displacement, can he still return to the life he originally hoped for?
The three-character title "wife" added to all the auras of Hattori Heiji above is the life that Toyama Kazuha has always had and finally realized. But layers of misunderstandings and life-and-death choices suddenly broke into her life. Can she and her sweetheart, her closest relatives, continue to hold hands and grow old together?
No matter what the ending is, there is always an eternal light in their hearts, waiting for each other to go home. This may also be the kind of life they hope for most, very calm but so warm.
