Byun Baekhyun was already content with his life.

At age 31, he's a full-time CEO of the clothing brand he and his friend started in their University days.

At age 31, he's happily together with his beautiful girlfriend.

Although he had an annoying grandmother who constantly pestered him into creating a mini version of himself, he still loves her with all of his heart.

However, also at age 31 was where things started to fall apart.

He made a mistake... in a shape of a country bumpkin with a stomach as big as a watermelon named Lee Jieun.
