She will be playing Hong Ae Ran, who is now the CEO of an internet shopping mall, but used to be the maknae of 1st generation girl group, Angels.  She'll be showing a fashionable side, which does not stray too far from her normal self!

Although she's made cameos before, she had never had an official role, so this is exciting!  A rep stated, "Her determination is unlike any other as it's been a while since she's acted out an important role.  She is diligently preparing to the point she's living with the script on her everyday."

It will start airing on January 20!
