Actors Song Joong Ki and Lee Yoo Bi are crowned as the best lovely siblings.

A still cut of Song Joong Ki and Lee Yoo Bi of KBS2 new Wednesday Thurdsay drama 'Nice Guy', was released. Lee Yoo Bi appears as his younger sister in the drama.

Song Joong Ki plays the role of bad boy who seeks revenge for love, Kang Ma Ru, who is also a normal medical student. He appears as the older brother who takes special care of his younger sibling, Kang Choco(Lee Yoo Bi), and also is a 'younger sibling-fool' that sacrifices a lot for her.

In the picture, Song Joong Ki and Lee Yoo Bi both have clear and bright skin like milk. They also show their large eyes and distinct facial features, that make them seem like real siblings. Lee Yoo Bi is actress Kyun Mi Ri's daughter, and has recently left an impression on MBN's 'Vampire Idol.'

Netizens who saw the picture of them said, "They are the best looking siblings," "Their aura is very similar," "What a good looking guy and pretty girl."

Meanwhile, the orthodox melodrama, 'Nice Guy,' is to air after the drama 'Bridal Mask' ends.
