Actors Im Si Wan and Seol In Ah shared an unexpected moment on the set of tvN's Love in Disguise after accidentally kissing during a rehearsal, leaving the director and production team laughing.

On October 28, tvN released a behind-the-scenes video showing the two stars preparing for their scenes and sharing playful moments between takes.

One moment that caught attention happened while filming a scene involving Seol In Ah's character, who goes outside to catch a cat while drunk.

During rehearsal, Im Si Wan and Seol In Ah were practicing their movements when they accidentally kissed before the cameras officially started rolling.

The director immediately reacted with a hilarious comment, saying, "I told you to do it after I say action! Why are you doing it when we haven't even started yet?"

The unexpected moment brought laughter to the set and highlighted the actors' comfortable chemistry.

The video also showed the two stars teasing each other during filming breaks.

Im Si Wan jokingly claimed that Seol In Ah had told him not to contact her, explaining, "I was banned from contacting Jae Hee, so I couldn't get in touch."

Seol In Ah then revealed that he had actually sent her a message telling her not to feel upset if he stopped contacting her.

She recalled him asking, "How was it? You were bored because I really didn't contact you, right?" before admitting, "But I really was bored."

Following the accidental kiss and the actual filming, the two carefully reviewed their scenes together. Seol In Ah expressed her wish for the moment to look good on screen, saying, "We have to look pretty together." She even requested another take to improve the scene.

Meanwhile, Love in Disguise is a romantic thriller about a wealthy third-generation heir suspected of murder and a former special forces detective who goes undercover as his personal secretary.

The latest behind-the-scenes video has offered viewers another glimpse of Im Si Wan and Seol In Ah's playful chemistry while working together on the drama.
