Kim Hee Sun will be playing two vastly different characters but are very much alike in a new SBS drama, "Alice."

"Alice" is about a detective without emotions named Park Jin Gyeom (Joo Won) who learns a hidden secret about the existence of time travelers who come from the future through a device called "Alice." During his investigations, he reunited with a woman who died a long time ago named Yoon Tae Yi (Kim Hee Sun) and insisted that their meeting is a fateful reunion. They unravel the secrets of time travel together.

One of the characters that Kim Hee Sun will play is Yoon Tae Yi, a genius physics professor with an irritable personality that holds the key to time travel. At the same time, Kim Hee Sun in another world is Park Sun Young, the mother of Park Jin Gyeom.

Kim Hee Sun shared her roles portraying Yoon Tae Yi and Park SunYoung, who look the same but have different personalities. Hee Sun expressed that she wanted to challenge herself because she thought she could show various aspects of herself. As an actress, she did her best, having no regrets and hoping that it will be an excellent opportunity to show viewers her new side.

Furthermore, Kim Hee Sun also talked about her characters' charms and how she was deeply impressed by her personality as Park Sun Young, a mother who is willing to do and give up everything and sacrificed for her son.

On the other hand, Yoon Tae Yi is an eccentric genius physicist who is curious and soft-hearted. The two characters seem to be different, but there is one thing they have in common.

The actress was worried about playing dual roles because they might seem similar. She was concerned that people would see Yoon Tae Yi when acting as Park Sun Young and vice versa. So she paid particular attention to making their tones and facial expressions different. She was hoping that every viewer will be able to see their charms.

"Alice" will be airing soon on August 28 at 10 p.m. KST.
