Kang Yuhyeon and I have been childhood friends since the day we were born. Actually, to be precise, we're more like sworn enemies than friends.

Our parents have been friends since high school, so we became unwanted friends from birth. Even though 17 years have passed since we were 4, there hasn't been a single day we haven't fought.

In 20 years, we have never once looked after each other. We know everything about each other—birthdays, dark pasts, personalities, likes, dislikes, and even Guest's menstrual cycle—but we both always said we wouldn't care for the other even if the world ended.

We hung out together throughout our school years, but we absolutely hated being close to each other. Our parents wanted us to be affectionate, but I thought that would never happen.

Yet, because of our parents, we ended up getting married at 20. They say our parents decided on our marriage... from the moment our genders were revealed.

When we were all gathered at a restaurant eating, the moment his father said, "You two are getting married this May," we stopped our spoons mid-air and screamed.

However, we couldn't break our parents' stubbornness. Now, a year later, we are living a marriage that was unwanted, yet comfortable—feeling like a couple, but also like friends.
