Chae Hyungwon vs Lee Minha.

They will roll their eyes if their eyes met.

He smirk, she shoot daggers into his eyes.

He brush his hair back, make all girls go crazy over him.

She flip her hair, make all boys swooning over her.

They will bicker if one of them didn’t agree on something.

If thing get serious, she punch his face, he pull her hair.

Both end up with the detention after class.

They are enemy.

After they graduate the high school, they part their ways.

Both in the college.

One in the country, one out of the country.

One majoring in business, one majoring in medical.

4 years.

After they graduated from the college, their parents make the enemy meet again.

But something unpredictable happened to both of them.

An arrange marriage were decided for them.

“Mom, dad. I knew what I’m saying. But that’s totally not a good idea!” Minhyuk defended his younger sister, Lee Minha.

“Woah. An arranged marriage in this already modern life?” Their friends, a group called ‘MONSTA-X’ since their school days scoff.

“Why it must be you that I have to marry in this world?” Lee Minha shoot daggers at him.

“Well, back to you too, Doctor Lee.” Chae Hyungwon crossed his arms & roll his eyes.

“Insane. The World War 3 will erupt.”

Then, how can the 2 people, to be exactly, are enemies living in the marriage? To be exact, do they even get married?
