tvN's newly-aired drama "It's Okay to Not Be Okay" recently shared its behind-the-scenes video for the first and second episodes.

"It's Okay to Not Be Okay" depicts a strange fantasy romance story about Moon Kang Tae (Kim Soo Hyun), a psychiatric community health worker, and Go Moon Young (Seo Ye Ji), a storybooks writer for children. She suffers from an antisocial personality disorder. Moon Kang Tae, on the other hand, has a brother who is a very gifted illustrator and is part of the autism spectrum.

The behind-the-scenes video started with Seo Ye Ji and Kim Soo Hyun, filming a scene wherein Moon Kang Tae is holding a knife until his hand bleeds. Kim Soo Hyun gets advice from the director about what will look most natural to him in acting the scene.

Away from the scene is Seo Ye Ji, who seems to be curious about filming equipment. Kim Soo Hyun then calls his leading lady, telling her not to waste her energy.

Later on, Seo Ye Jin lets go of the knife too hard and ends up bursting into laughter. Kim Soo Hyun asked her why she is laughing.

In the next scene, Kim Soo Hyun and Oh Jung Se, immersed in their characters, are at Go Moon Young's autograph event, when Moon Sang Tae gets overwhelmed by the crowd. Moon Kang Tae then comes in his rescue to comfort him and tries very hard to hold back his tears.

Meanwhile, actress Seo Ye Jin cannot hold her laughter when she's supposed to give Moon Kang Tae a small smile. When the director calls cut, Kim Soo Hyun shouts to make the scene pretty with CGI.

In other scenes, Oh Jung Se and Kim Soo Hyun ride a bus while joking around and reading a book about dinosaurs. Their brotherly relationship is such a wholesome thing to see, which will surely win viewers' hearts.
