JTBC’s Monday-Tuesday drama “The Beauty Inside” has released a new behind-the-scenes making-of video of its cast!

“The Beauty Inside” tells the story of a woman who lives with the face of someone else one week a month and a man who has prosopagnosia, the inability to recognize faces.

In the clip, Lee Min Ki and Seo Hyun Jin practice exchanging lines. Seo Hyun Jin suddenly smacks Lee Min Ki’s arm after he says something silly as his character Seo Do Jae, causing him to jokingly shout out “Ouch!” The director makes both of the actors laugh when he says, “Hit him harder.”

In another scene the two shoot together, Seo Hyun Jin continuously pesters Lee Min Ki to look at her while he watches a movie on his laptop. After her constant poking, he lets his laptop plop down to the ground as he faces her and gives her a kiss. Seo Hyun Jin bursts out laughing and remarks, “Isn’t this too funny,” referring to the expensive laptop falling off his lap.

The Ahn Jae Hyun-Lee Da Hae couple also make an appearance as they sit in a car to film their kiss scene. The two are clearly nervous about such an iconic scene, but can’t hide their amusement as Ahn Jae Hyun says, “[Our characters] haven’t even held hands yet, but we have a kiss scene.” The two then express their disappointment at how they don’t appear much in the making-of videos, and ask the staff, “The Do Jae-Se Gye couple appear a lot, huh?” Wearing a cute pout, Lee Dae Hae jokingly tells the staff, “Just leave,” before waving goodbye.

Later, Seo Hyun Jin is told that this is her last scene with Gging Ggang, her character’s pet dog in the drama. She expresses her disappointment, but enjoys her time with the fluffy dog until the end.
