It's Okay to Not Be Okay it by far my favourite drama I've ever watched. Where should I even begin explaining.

First of all, the Characters: This isn't your typical the boy gets the pretty girl story, here the girl Ko Munyeong is a savage, speaks her mind type who gets whatever she wants no matter what, even if she has to kill. The male protagonist, Moon Gang Tae, is a unique character, he has quite some childhood trauma so he's able to hide his feelings very easily, he's also one of the few people who isn't scared of Ko Munyeong. Moon Sangtae is Gangtae's elder brother who has an autism problem, he acts like a child and has a fear of butterflies due to some circumstances.

Next the acting: Kim Soohyun and Seo Yeji have GREAT chemistry and can tackle such hard roles. Oh Jungse probably has the hardest character to portray in this drama but he executed it very well.

Finally the story: The story is full of twists and turns and includes a mystery, and romance part of it, the story is so well written that I can't get enough of it. It's also really unbelievable how 2 of the main characters even fall in love in the first place. IT'S VERY REWATCHABLE! I know that I'm not speaking for only myself but a lot of people watching that they are not ready to let this drama go when it finished.
