The upcoming comedy-drama “Perhaps Love,” directed by Cho Eun-ji, revolves around a bestselling author whose life changes dramatically when he falls in love.

“The cast and the crew, including myself, were always laughing while shooting. I actually got a note of warning from the sound recording director because I giggled too much even in a serious scene,” Cho said in an online press conference Tuesday. “We were able to finish our project with a lot of laughs. I am certain that the audience can also feel this positive energy and laugh a lot.”

In the movie, the complex relationships among the three lead characters -- Hyun, Mi-ae and Soon-mo, played respectively by Ryu Seung-ryong, Oh Na-ra and Kim Hie-won -- bring out laughs in unexpected ways.

Veteran actor Ryu Seung-ryong spoke of the excitement of returning to the big screen as a divorced bestselling author.

“The unusual relationship between the characters attracted me the most to star in ‘Perhaps Love,’” Ryu said.

“I was curious to know who would take the role of my ex-wife, Mi-ae. Because I always thought of Oh Na-ra as an outstanding actor, especially after watching her hit drama ‘Sky Castle,’ I was thrilled to hear the news that she would co-star in the movie. It turned out that she was a perfect fit to play Mi-ae,” the actor added.

For Oh, working with Ryu was both a great honor and an interesting experience.

“I actually played a minor role in Ryu’s previous film, ‘All About My Wife’ (2012). I was happy to meet him as a lead character and tried to put my utmost effort into playing the role, which I wasn’t able to do in ‘All About My Wife,’” Oh said.

According to Kim, the audience will see a new side of him in “Perhaps Love.”

“Shooting a romance film was always on my wish list, so I enjoyed every bit of my role as Soon-mo. As Hyun’s close friend, being in a secret relationship with Mi-ae may sound ridiculous at first, but you will understand everything about this relationship between the characters after watching the film,” Kim said.

The actors and the director all agreed that the film would offer comfort, heal people’s hearts and put smiles on moviegoers’ faces.

“Perhaps Love” is scheduled to hit local theaters in November.
