I started watching this drama because I watched Maiden Holmes. Maiden Holmes and My Unicorn girl have the same FL. Even in Maiden Holmes FL disguised as a boy and she looks good in disguise. So I have started watching My Unicorn girl drama.
I have not disappointed at any point. ML is very handsome and the side couple stories are also good.
Beware that most of the part FL is disguised as a boy. Only for a few scenes, she has seen as a girl.
But I liked her as a boy. This is entirely my opinion.

If you want to watch a short and sweet drama go for it don't hesitate.
