Actress Lee Se Young has sparked a huge debate over the nature of her interaction with veteran actor Choi Min Soo during recent media appearances to promote their new K-Drama, Motel California.

In a clip posted Friday to MBC Drama's verified Instagram account, Lee and Choi, who plays a father and daughter in the show, strike pose after pose for still-lifes.

In the video, which triggered mixed reactions from fans, Choi is seen rubbing Lee's arm and striking poses with her.

Some viewers felt that Choi's behavior was too familiar and that it appeared to make Lee feel uncomfortable.

There was a flood of comments on social media, as one user said: 'It feels like sexual harassment just saying,' with many others agreeing that they were uncomfortable with the way the interaction went.

Many defended Choi, though, claiming what she did was taken out of context.

Proponents added that Choi's gestures were meant to ease the atmosphere since Lee seemed to be having a tough time relaxing at the event.

A fan wrote: "Yall need to watch the video all the way through. Se Young was shaking so much he had to joke with Choi Min Soo. Se Young shouted, 'Dad, 'stop it, stop it!!"

Meanwhile, Lee has said in interviews that Choi is like a real father to her on set.

Supporters for both performers are asking for more nuance in the couple's bond and the context surrounding their conduct.
