[Re-writing as of September 29, 2015]

Ever since birth, they've shared things with each other. Toys, clothes, shoes - you name it! They're twins after all.

Yongnam, as the older brother, always cared for his little brother - Yongguk. Always giving in to him, giving what his little brother wants. It's not that Yongguk pushes him, Yongnam just loves his little brother more than the material things.

Yongguk knows that his hyung is like this so he doesn't really ask for much. He understands that his brother will give him anything in the world, because he is his brother. No more explanations needed.

They've always been close. Always getting along and never fought in their 24 years of living.

What if one day, a girl comes along and the little brother suddenly becomes attracted to her? Cliché thing is, the girl falls for the older brother.

Will Yongnam give way for his brother as usual? Will Yongguk ask for his hyung to move aside? Will this girl eventually fall for Yongguk? Or will Yongnam fall for the girl too?

Will blood still be thicker than water if love is at stake?
