I really loved this drama! Both times that I watched it.
The story I find is really good (contrary to what a lot of people think), I even find the repetitiveness more heartfelt with each repeat. It's a lovely story and I don't find the love triangle annoying whatsoever.

There was a plot twist about who was behind the killings. which is always kind of nice.

I wouldn't download the drama's OST, but it fit the mood of the story.

Overall, I would definitely recommend watching the drama, I really enjoyed it!
