I'm glad I jumped on this train while this drama still has hype because the content is truly something. The first thing that stood out to me was the title. Mental health and overcoming the past are the two most important themes in this drama, but the way they were handled by the writers is really remarkable. Just about anyone can pick out a character that relates or speaks to them because they were created so realistically and they are so humanely flawed that anyone can resonate with at least one character. In one way or another they are struggling to deal with traumas from their pasts and they are all crippled because of it. I'm pleased that the writers committed to the theme and the episodes were very in-depth when it came to dealing with mental health. This drama provided so many scenarios that showcased the many different types of trauma, and executed it in a way that goes straight to the heart and leaves you breathless.

The leads, as well as the others are so well developed. This is my first Kim So Hyun drama, and I'm so impressed with the range and raw emotion he was able to show through this role. I'll definitely be checking out his other works in the future. Oh Jung Sae as Sang-tae was amazing. His portrayal of an autistic adult deserves an award and I mean it. Gang-tae's relationship with his brother was so pure and wholesome. I smiled a lot during this because of them. Munyeong was truly something. She reminded me so much of myself. This wasn't just a love story about two broken people fixing each other, but a tale that teaches us to not only remember our past but to overcome it. After all, the past shapes who we become. For "if you can't overcome it, you'll always be a kid whose soul never grows."

Rewatch value is strong. I'll definitely watch this again in the future. Definitely recommend. 10/10.
