It’s Okay to Not Be Okay Recap: The Truth About Ko Mun-yeong’s Mother
Ko Mun-yeong’s mother, Do Hui-jae, is actually Park Haeng-ja, the head nurse of OK Psychiatric Hospital, and she’s the one responsible for the death of Choi Hee-jin, Gang-tae and Sang-tae’s mother.
Years ago, Hee-jin started working as a housekeeper at the “Cursed Castle”. One day, Hee-jin finds Mun-yeong outside and the latter tells her that maybe she should just kill a bird with a broken wing because it couldn’t fly anyway.
This concerns Hee-jin, so she tells Hui-jae about this and that there’s a hospital her son goes to. This results in Hui-jae killing her, as she thinks that Hee-jin was talking as if Mun-yeong was a lunatic.
Ko Mun-yeong’s father, Ko Dae-hwan, found out about this and was terrified. He had a brain tumor, and he did not want his daughter to become a monster like her mother when he died.
Hui-jae/Haeng-ja laughs about this, so Mr. Ko pushes her over the railing. Mr. Ko believes he killed his wife, so he hides her body in the basement. Later on, we see the body inside a suitcase, dumped in a lake.
But it turns out, Hui-jae didn’t really die, and she’s been watching them all along with a new face and name. Hui-jae/Haeng-ja ends up in prison for her crimes, and when Mun-yeong visits her, she tells her that she will erase her from her memory.

It’s Okay to Not Be Okay Ending Explained: Why Did Sang-tae Leave?
Things do not really stay the same between Gang-tae, Mun-yeong, and Sang-tae as the latter decides to leave the two at the end of It’s Okay to Not Be Okay.
The trio receives a camping car from Director Oh. So, they go on a long trip with no destination, as this is what Gang-tae always wanted to do.
While Sang-tae enjoys their trip, he reveals that he wants to go somewhere else. He wants to work as an illustrator and make more children’s books, and another author already wants to work with him.
Mun-yeong says that she also needs Sang-tae, but Gang-tae asks his brother if he will be okay without him. Sang-tae acknowledges that “Moon Gang-tae belongs to Moon Gang-tae” (something Gang-tae screamed at his mother when he was younger).
Sang-tae emphasizes that Gang-tae doesn’t belong to him, and the latter starts crying. Sang-tae thanks his brother for everything, and Mr. Lee arrives to pick him up.
It’s Okay to Not Be Okay ends with Sang-tae going separate ways with Gang-tae and Mun-yeong, as he pursues a career as an illustrator, while the two carry on their trip.
Throughout the series, we see that Sang-tae is possessive when it comes to his brother. He even gets jealous of Gang-tae and Mun-yeong’s relationship because he believes that his brother belongs to him.
Growing up, their mother always told Gang-tae that the reason he was born was so that he could take care of his brother. So, Gang-tae always believed that his only purpose in life was to look after Sang-tae.
In the finale, we see that they let each other go – not because of conflict, but in order to grow. Gang-tae can finally try new things and pursue what he wants, while Sang-tae can learn to be independent.
The series, after all, is about growing as a person, fighting your battles, healing from painful experiences, and moving on from the past. In the end, we see the main characters in a good place, and they’re off to becoming better versions of themselves.
