Jae-young and Da-jin have been going out for 6 years. Living in apartments next door to each other, Da-jin is an editor at a publishing company while Jae-young works as a producer for a home shopping network. Their sex life is not as hot as before, but they're comfortable in their relationship and know everything about each other. Da-jin doesn't mind asking Jae-young to buy tampons for her, and Jae-young visits Da-jin's mother from time to time to repair the house or just to say hello.
