This was the first k-drama I've ever seen. It soon became one of my comfort shows, and I still love rewatching it again and again, even though I now know it by heart.

It was made at the beginning of the 2010's, when there were flip phones with batteries you could take out of the phone just to be dramatic, and they do that a lot in this (take out batteries as well as being dramatic).

The premise is really fun and quite original, and the two main actors are amazing and very believable at playing all the roles they are given. Not once I am confused as to which character they are embodying. I love it.
