Kazuki (28), a novice novelist, is spending his summer vacation on his home island to write a new novel. By chance, Kazuki is put in charge of the pension where he is staying, and he meets two guests, Reiko (28) and Yuka (24). Kazuki sees in Reiko the image of a woman he used to date, and easily falls in love with her. One night over drinks, the three begin to clash greatly, triggered by Yuka's unrestrained behavior.
