Being in love with 21 people and kissing 13 of them in a day sounds like mission impossible, but Han Hyo-joo made it happen in her new film "The Beauty Inside," which is set to be released next week.

The fantasy melodrama is about a woman who falls in love with a man who changes his appearance each day.

He mostly appears in a shape of a young man, but sometimes transforms into a woman, a child, an elderly person, and a foreigner.

"I had no previous experience of working together with any of them," Han recalls. "There was one person that I had really good chemistry with, which was Park Seo-joon who played the man on the day when they declare their love for the first time."

"We spent a lot of time together because we had a longer scene. I'd love to do a proper full-length film with him."

Han said she really enjoyed shooting the film, which was quite an unfamiliar experience for her, and was very happy to have an opportunity to tackle a new genre.
