Overprotected Kahoko

Masataka Nemoto, who works at an insurance company, is worried about the future of his only child Kahoko; Kahoko's parents doted on her, and she grew up in a very overprotective household. Masataka fears an abnormal codependence.

Kahoko begins to seriously contemplate her future and visits her father and other relatives' workplaces with her mother Izumi; Kahoko learns that her cousin Ito will be participating in a competition with a wrist injury.

Kahoko realizes she is falling in love for the first time; Izumi learns of this and strongly opposes to it; she fires one insult after another about Hajime; for the first time in her life, Kahoko yells at her mother.

Kahoko and Izumi's strong bond is crumbling, and Masataka is caught between the two; Kahoko feels heartbroken for the first time in her life when Hajime rejects her.

Masataka snaps at his wife and daughter, and finally leaves home; Masataka's relatives problems gradually come to light; thanks to Hajime's influence, Kahoko starts to realize just how sheltered she has been.

Izumi suddenly leaves home after hearing Kahoko's declaration that she wants to become independent; with the mother gone, the house is a complete mess, and Masataka and Kahoko have to work hard at chores they're not used to doing.
