Kin no Kanojo Gin no Kanojo

A clumsy protagonist becomes involved with a striking young woman in a romantic comedy. After she falls into a lake, a mystical figure known as the "Lady of the Lake" appears and asks if he lost his golden or silver girlfriend. This question causes the girl to split into two distinct versions of herself. One is elegant and refined, embodying grace and poise. The other is brash, irreverent, and unfiltered in her speech and behavior.
