When I watched the trailer, I knew I had to watch it but I kept delaying it. And finally! I watched it.
First of all, it's just 10 episodes and even if the duration was one hour each episode it passed really quick.
The storyline was refreshing for me. I haven't known that anything like trauma cleaning existed before I watched the drama. Each episode deals with death, grief, guilt and family.
Along with the main topic it also sheds light on different topics like adoption, nationality, LGBTQ community, etc .
The characters were very likeable. Ge-ru suffers with Asperger syndrome and is a literal genius. He loses both his parents and have to adjust living with his uncle. His characterization was done very well and Tang Joon-sang nailed the role.
Each member of the cast did their best. Acting was top notch.

The drama is heartwarming and heart-wrenching at the same time. Absolutely loved it❤️
