I know I cannot express enough words for my appreciation with this drama. So, I would like to extend my love to this post.
It's such a breath of fresh air for the K-Drama world that this drama tackled a delicate and complex issue of mental health. I believe this is the perfect time to show and learn about this topic since we are all experiencing and somewhat suffering from this global pandemic.
I felt every emotion this drama wanted to share with their audience.
Feelings of lost, despair, storge, hate, and ultimately, love.
I will always be in awe with all the cast and crew who helped built and produce this drama. 
This is a must watch even for non K-Drama fans. This is a proof that dramas should not be trapped in a cycle-like storyline and common emotions.
