The actress Park Bo Young revealed she became attracted to Song Joong Ki after a slapping scene in a movie.

On the latest episode of 'Entertainment Relay', the two leads of the film 'Wolf Boy' sat down to discuss their filming stories. "There was a scene where I had to slap Song Joong Ki, so I had a hard time," Park Bo Young said.

"She's too nice, so she couldn't hit me properly," Song Joong Ki recollected. "I told her to hit me for real, so she really did put her entire energy into it."

"It was my mistake," Song Joong Ki finished, bringing laughter on the set.

Park Bo Young explained, "He told me to slap him for real, so I did. That's when I fell in love," she said. "He's a person with very nice manners and who knows how to take care of people."
