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!
