This story is about guilt, trauma, crazy people, and love.
I think too many criticize this drama. I loved how the story unfolded. It is like an onion with multiple layers.
For me, it was worth watching for the cast alone. It had a morbid tone but also humor.
I have watched it twice and found it good both times. Trauma is often portrayed as something just to get over, but this drama shows how it stays with you and you can live with it. The FL and ML have good chemistry, and that shows.
Watch it and enjoy the quirks and smiles underway.
