Watch: "It's Okay To Not Be Okay" Promises Love, Drama, And Growth In New Highlight Reel

tvN has released a highlight reel ahead of the premiere of “It’s Okay to Not Be Okay”!

“It’s Okay to Not Be Okay” revolves around the love story between Moon Kang Tae, a community health worker at a psychiatric ward, and Go Moon Young (Seo Ye Ji), a children’s storybook writer with antisocial personality disorder. Oh Jung Se will play Moon Sang Tae, Moon Kang Tae’s older brother who has autism spectrum disorder (ASD).

The highlight reel begins with the opening of a mysterious children’s book. Moon Kang Tae’s voiceover narrates, “The boy woke up from a terrible nightmare once again. One day, he visited a witch and begged her.” The screen switches over to show Go Moon Young, an author with eerie charms.

After a fateful meeting, Go Moon Young continuously shows up in Moon Kang Tae’s life. Fed up with her advances, he tells her, “I’m guessing everyone just went along with your careless acts, but they won’t work with me.” Despite his cold facade, he turns gentle and patient when it comes to his older brother Moon Sang Tae.

Then one day, Moon Sang Tae, who is a fan of Go Moon Young, decides to visit her at an important meet and greet. Disorder erupts at the event, and Moon Kang Tae quickly rushes to his brother’s aid. Things go from bad to worse as Go Moon Young gets swept up in a scandal for being rude and obnoxious.

The teaser also shows the painful pasts of Moon Kang Tae and Go Moon Young. As the two start to get to know each other, Moon Kang Tae attempts to calm down Go Moon Young’s fiery temper, while Go Moon Young beckons him to give in to his heart and have fun once in a while. Towards the end, Go Moon Young says, “Fate isn’t anything special. When you show up in front of me when I need you… that’s fate.”

“It’s Okay to Not Be Okay” premieres on June 20 at 9 p.m. KST.
