The First Investigative Division is the star unit of the Tokyo Metropolitan Police Department. Jun'ichi Ōiwa, the head of the division, leads around 400 elite detectives. He has an extremely heavy responsibility: attends initial investigations at the scenes of all brutal crimes that occur within the metropolis, decides on the course of action of the investigations at the same time as he directs many investigation task forces and gets into investigations himself at the critical phase. However, Ōiwa is definitely not a superman. Amid his suffering, Ōiwa overcomes this grave responsibility and is quite simply a "life-size hero" and "ideal boss" to his subordinates.

Excitement pervades through a university preparing for the annual school festival. Meanwhile, a calm atmosphere hangs over the club room of the film studies group which does not really have an exhibition. But Sara, who dreamed there was something in the corner of the club room, finds an old cardboard box that morning.

University student Nagisa becomes the tutor of high school student Kokusai. Despite their contrasting personalities—Nagisa being serious and responsible while Kokusai is carefree and charming—they develop a close bond. As they spend more time together, Nagisa finds himself drawn to Kokusai in ways he hadn't expected. Their relationship faces challenges as they navigate personal feelings, societal expectations, and their own uncertainties about love.
