The new Hong Sisters drama has cast both leading roles. And just in case you are not familiar with the great k-dramas these sister-screenwriters created, that's something to be excited about. Their drama hits include "You're Beautiful," "The Master's Sun," "The Greatest Love" and "My Girlfriend Is A Gumiho."

Their newest drama is titled "Warm and Cozy."

The leading female role has been cast for a while. Kang So Ra, who appeared in "Misaeng," "Doctor Stranger" and 'Ugly Alert" signed on early in the casting process.

Kim Woo Bin was up for the lead role but Yoo Yeon Suk has been confirmed as his replacement.

Yoo Yeon Suk has attracted plenty of attention for his recent performances in the films "Architecture 101" and "A Werewolf Boy," as well as his drama roles in "Gu Family Book" and for playing the character Chilbong in "Reply 1994."

According to the drama's production company, Bon Factory, the actors have the necessary chemistry to make the drama a success.

"Yoo Yeon Suk and Kang So Ra not only look the part but have the natural charisma required for the characters Baek Geon Woo and Lee Jung Joo," said the Bon factory representative.

In "Warm and Cozy," he plays Baek Geon Woo. Baek moved to Jeju to open a restaurant just because a girl he likes lives there. The drama was originally called "Jejudo Gatsby" because the character of Jay Gatsby in the novel "The Great Gatsby built a mansion just to be close to the woman he admired. Baek Geon Woo is smart, candid but a hopeless romantic.

Warm and Cozy is the name of his restaurant.

Kang So Ra plays the long-suffering heroine Lee Jung Joo. She acts tough but she's a softie inside and it gets her in trouble. She spent five years living in Seoul, working hard to make her clothing company and her relationship a success, only to lose that job and her man. She's forced to return to her home, stunning Jeju Island, and start all over again. That's where she meets Baek Geon Woo.

Park Hong Gyun, who previously worked with the Hong Sisters on "The Greatest Love," will direct "Warm and Cozy."

"Please look forward to the perfect harmony that will be created by the energetic actors, Yoo Yeon Suk and Kang So Ra, the Hong Sisters and Director Park Hong Gyu," said the Bon Factory representative.

"Warm and Cozy" is expected to air in May following "Angry Mom."
