It is a good kdrama. Romance, drama, action and comedy is in it. You should try watching it. Since I love everything about science and my dream is to be a doctor. I really enjoyed the drama until the end. I don't know for you. We have different comments about it, but I can assure you that it is worth watching it.
I rate it 10/10. Just check it out. :)
And then reply back if you liked it. :)
