    It's Okay to Not Be Okay drew an average viewership rating of 5.4% and soon became a Hallyu K-Drama following overseas popularity. It topped the Content Power Index (CPI) and also ranked first on Good Data ranking during its entire run. With four episodes released it ranked in the top 10 most talked about programs according to the results of a survey on internet reactions conducted by the government agency Korea Communications Commission for TV programs of the first half of 2020; while as a result of an analysis by Smart Media Rep on online platforms such as Naver and YouTube, the average number of playbacks per episode was found to be 3.37 million with a majority share of viewers from the 20s.

    Following the popularity of drama the outfits wore by Seo Ye Ji also caught attention for its uniqueness making Korean fashion designers and brands of earrings, handbag and nightwears famous internationally. The children's storybooks that appeared in the drama were listed in the top 20 bestselling books of the month, according to the Kyobo Bookstore and YES 24 websites.

    Critical Response

    The Chilean newspaper La Tercera cited it, including in its list of the most applauded Netflix series, as "one of the most popular Asian drama" of 2020. Worldwide magazine ELLE ranked it #2 on its list of The 10 Best K-Dramas To Binge-Watch On Netflix. While Vogue India recommended it in its list of 12 feel-good Korean dramas to watch on Netflix and Rakuten Viki. Also, GQ India ranked it #1 on its list of 5 Korean dramas on Netflix with an IMDb rating of 8 and above that you shouldn't miss.

    It's Okay to Not Be Okay was recognized for its visual storytelling, unique characters and was praised for the acting by the cast.

    The Manila Bulletin wrote that "While clichés are necessary in romantic K-dramas, IOTNBO was unafraid to introduce fresh elements and twists." The Cosmopolitan Phillipines reviewed it saying "It's unlike any drama we've seen before... close to perfection, but just like all of us, still a work in progress." The Straits Times gave the drama a rating of 3.5/5 stars, while South China Morning Post gave a rating of 3/5 stars pointing out that "The few detective fiction fans expecting to learn the morbid details of what exactly happened should brace for disappointment."

    Representation of Mental Health and Response

    Although the series is a romance drama and a work of fiction, it was praised for its depiction and representation of mental health and abuse. At the same time, some details, such as female lead's Antisocial Personality Disorder, have been questioned. The Hindu reported that, "The initial buzz around the show came largely from its premise and the fact that it would shed light on mental health."

    The SCMP in its review said that, "What's immediately interesting about the series is how it shines a light on mental health and depression... It's Okay to Not Be Okay highlights the fact that everyone has problems in life and how people deal with their issues," The Prothom Alo praised the series writing that, "In a world where people with autism are known as weak or helpless, this drama shows a point of view that they are kind human beings too... This drama makes people realise, societies should stop looking at those who seem different. Especially, those with special needs."

    When I had an interview during the early half of the project, I said he (Sang Tae) is a character suffering from autism. I learned that this was a wrong expression. Saying that you're suffering from something means you have an illness. However, autism isn't an illness, but something you're born with. I learned it's correct to say he's a character who was born with autism.

    Oh Jung Se

    An act of kindness by actor Oh Jung Se was a hot topic on social media after he spent a day with a fan, cellist Bae Boum Jun who was also an autist as his character in the drama, at an amusement park.


    The series was criticized on social media leading to the KCSC receiving over 50 formal complaints. One was a sexual inappropriate scene where female lead Moon Young overtly stares and touches male lead Gang Tae's body as he gets dressed. In another scene a male character, who suffers from manic depression and exhibitionism, reveals parts of his bare body, with his genitals covered by a drawing of an elephant. However, many viewers defended both the actions of the character and the production team by arguing that the scenes were to express character's personality.

    As a result, on August 26, 2020, the broadcast censorship body issued a legal sanction to the television series for sexually inappropriate scenes in Episode 3 regarding it against the broadcast deliberation regulations, including Article 27 on duties of integrity and Article 30 on gender equality. The reason explained by the subcommission was that, "Even considering the fact that they were meant to exaggeratedly express a character's personality, (the scenes in question) show how insensitive the drama's producers are to gender equality in broadcasting content that may belittle a certain gender and hold the possibility to justify sexual harassment and molestation."
