Lee Donghae..like all of ELFs in the world know, he is handsome, hot but also cute at the same time, child-like, innocent, pure, has a pair of beautiful eyes and beautiful personality. He's a perfect boyfriend and every girls in the world is willing to die just to date with him, even if only one day. But, unfortunately, this Lee Donghae is already taken. The taker is a man that everyone knows and everyone can guess, the famous Lee Hyukjae aka Eunhyuk. The 'eun' in Eunhae or the 'hyuk' in Hyukhae. And this Lee Hyukjae has opposite views about Lee Donghae. In his eyes, lee donghae is annoying, attention seeker, hopeless romantic and crybaby..

Lee Hyukjae..like all of ELFs in the world know, he's a handsome, y and hot anchovy..he can make a girl pregnant only by seeing him topless..(Kekeke)..he's a dancing machine, a talented rapper and soon-to-be a great MC. He's funny, moodlifter, has a casanova vibe and very kind. He never get angry eventhough the other members always bully him in variety shows..yeah, he's an ideal type for every girls in the world. But, unfortunately, he's already taken. The taker is a kid (not really a kid but he looks like a kid, right?) that everyone knows and everyone can guess, the famous Lee Donghae. The 'Hae' in Eunhae or Hyukhae. And this Lee Donghae has opposite views about Lee Hyukjae. In his eyes, Hyukjae is a cold-hearted man. Enough to say. If Donghae mentions all of his complains about Hyukjae, this story will never start.

So, how can these two people become a couple? How do these two people maintain their relationship? Can they be happily ever after?
