The Kims have these two siblings namely Kim Sol-bi and Kim Jaejoong. Sol-bi is 2 years older than Jaejoong. She's perfect in every way that's why her parents love her very much. She graduated from a famous musical school and currently persuading her carrier as one of the best musician in Korea. She and Yunho got together for almost a year now. The two met at Sol-bi's recital. Yunho was very mesmerized with the whole thing. He thought Sol-bi was an angel playing piano in front of him. That night, Yunho thought that he just met his other half and needs to have her for him to become complete. Being one of the most famous lawyers in Korea, he always gets what he wants. Though, he looks like a play boy outside but inside, he's very conservative. One of his principles in life is “No sex before marriage”. ;p
On the other side of the story, here comes the twin brother of Sol-bi, Kim Jaejoong. Though, he's not perfect in every way, like his sister, he still do his best just for their parents to notice him. Right after High school, he give-up competing with his sister. He admitted that he really can't compete with his sister, so he just do things the way he want it to be leading now to a newly born Jaejoong who is very Unique in every possible way, mischievous, clumsy and not to mention, very naughty. After everything that happened, Jeajoong can't hate his sister because, like I said, her sister is perfect in every possible way and that includes her angelic-like persona.
After graduating High-school, Jae decided to pursue his love in music. (ohw, I forgot to mention, Kim family is very famous in Korea because they are all well-known musicians)He enrolled himself in a prestigious musical school in Paris. Having enough money for everything, Jae still insist on working part time job in Paris as a waiter in a Café. In his school, though he's still a sophomore, he is very famous for composing beautiful songs. He can play almost every instrument. His “sempais” in the music club are very fond of him. They like his personality especially clumsy Jaejoong. Also, every Friday night, he would always have his night life where the endless flirting with handsome hot guys always occurs.
Having an in born talent of composing beautiful song, almost all of her sister's recitals are composed by him though, their parents don't know about it.
He met Yunho on his 2nd year. Sol-bi wants Jae to come home in Korea but being stubborn, Jae refuses. He just knows that going home won't bring him any good. His parents would just give more pressure to him. And being the lovey-dovey sister, Sol-bi went to Paris to personally meet his brother, bringing Yunho with her. Just as Yunho set foot on the Paris airport, his eyes meet the black doe-eyed one. He doesn't know what to do as this said person smiles warmly to him while walking towards his direction. Like world move very slowly, the walking angel did walk slowly too. He holds his breath the entire time and mind just go blank. And from there, the wheel of faith started to move.
