I love historic period dramas, and I was pleasantly surprised with this drama - and time travelling was amazing add to it. Sure, the plot has its issues and plot holes, but once you ignore them, you can really enjoy this drama. I also really loved that the main woman Soo Jung wasn't a shy or clumsy girl, but a witty, confident and even rude! We don't really see that in many dramas, and it was a positive thing to see that made me wanna watch more.
The characters are well written and fun, and even the annoying ones (I'm looking at you Go Il Yong) I found really likeable and grow fond of. And all the couples are so shipable and have great chemistry together, espeically Soo Jung and On Dal. Also the kisses between them were actually steamy and realistic than most Kdramas, another plus!
There were some plot holes, as I mentioned, but mostly I wish we knew more of Boong Boong (also one of my favorite characters, the car lol) - has it always been a time travelling car? Where did it get its powers, and why did it choose Soo Jung to travel her back in time, and travel her around? But well. I guess they wanted to leave that to a mystery.
