The Oh Company, the largest company in Korea, and the Xi Company, the largest company in China have devised a plan to create more profit by using a popularity boost by using their sons. And the sons, Oh Sehun and Xi Luhan, don't like it one bit. The two companies, engrossed with money, have done the worst publicity stunt (at least in Sehun and Luhan's perspective): engaged their sons to each other.

The audience was deathly silent, with exception of Luhan's and Sehun's spit-take with their beverage. “WHAT?!” The two boys shrieked. “Engaged to–”

“HIM?!” Luhan pointed at the taller.

“IT?!” Sehun pointed to the older.

They don't like it at first, but after their younger sisters' plan. They realize that it might become more than a publicity stunt.

Collaborating with mah sistar~!!!!! She's ‘playing’ Oh Hyomin, Sehun's younger twin.

And I'm playing Xi Luxuan, Luhan's younger sister

Some situations we (my sister and I) created are based off some of our own family events and some are not. If so, anything that look like you've read/heard it from somewhere else is completely coincidental.
