I was hesitant to watch this at first as I am not a big fan of Psychological dramas, after my lukewarm reception of "It's Okay, That's Love," however, after putting aside my prejudices, I came to appreciate this drama about dealing with mental health, familial issues, trauma, how to overcome one's past, embrace one's weakness to be strong in the future. It is a powerful drama about learning, about forgiveness, about caring, about unbreakable and breakable bonds, but ultimately, how It is okay not to be Okay.

Performances by the three main leads are phenomenal, but a standing ovation must go to Oh Jung Se as he nailed Moon Sang Tae's character down as if he was autistic and suffering from PTSD himself. His gestures, mannerisms, quirks and ticks all make his character as the mentally-challenged artistic genius so believable, while retaining his forthright innocence. Kim Soo Hyun somehow became more handsome when I saw him last in 2013's MLFTS. First time seeing Seo Ye Ji, but she also was born to play the eccentric author Ko Moon Young, with a dangerous mix of sexy and devil.

Supporting characters have each of their own strength and personalities that all together, made the drama cohesive. Fashion and cinematography are also worth noting. Had to deduct half a point due to the dip in pacing towards the last quarter of the drama. If you are looking mainly for romance, this is not the drama, but unless you are inhuman, your heartstrings will be tugged seeing flawed characters leaning on each other for support, how your circumstances do not necessarily make who you are, but how you make out of it.
