I'll try to give a short review just about my opinion because most has already been said. The first episode was one of the weirdest and most packed I have ever seen in a drama yet. And honestly, I don't know if that's a good or bad thing. It broke my perception of a 'normal' rom-com drama though that's for sure, and a rom-com was what I was expecting from the cover poster and title. The drama consistently messed with my brain and I had to go read detailed recaps after each episode because I always missed a detail here and there (because details are so important to notice in this drama). It's not an easy watch and you really have to pay attention in order to enjoy this drama. I also recommend widening your drama scope (I had to!) so you can brush aside all the preconceived notions you might have had about dramas. This drama borders on two parallel worlds within the characters so it might be a little hard to digest in the beginning. After 3 episodes, I got more into the drama. Many of the characters weren't likable but I guess that's what this drama aimed at: to show the flaws of human nature, and to allow the audience to understand a bit more about mental illnesses, which is a taboo topic in many Asian countries. I have never watched any of the actors/actresses before but I have no complaints. They were all seasoned actors and the leads, Jo In Sung (Jae Yeol) and Gong Hyo Jin (Hae Soo) were both amazing in their portrayal of their emotions. I don't think I would re-watch this because a lot of it was discovery and wouldn't be as surprising in second watch. I appreciated that this drama tried to tackle mental illnesses. Even though it may not always be medically accurate, it was still a drama that shined a positive light on mental illnesses that is very encouraging. Most importantly, this drama contained a lot of heart. I wholeheartedly recommend this drama but only if you're in the mood for a quirky romance that is about embracing one another no matter the flaws. 9/9.25
