Arika, a married woman who lives an ordinary life, lives with her husband's younger brother, Masato, who has moved to Tokyo to become a stage actor. Her husband came home late, so Arika often spent dinner time with Masato. One day, at dinner, Arika heard Masato say, ``I'm going to have a kissing scene in the audition, but I'm worried because I have no experience.'' Arika learns that she had been drinking too much.
