8/10 Because plot holes are inevitable in time traveling dramas Although this is an adaption, you wouldn't notice that unless you already knew about it before hand. I think they did a very good job on this live action and the characters are very talented considering how young they are. Like I said, there is some time manipulating going on in this drama so of course, plot holes are inevitable but if you see past that, I think you will enjoy this as much as I did. It's a very beautiful story with smooth progression and character development and I liked it to the very end. ENJOY!
