This drama is must watch for all K Drama Lover even to your mom & love ones, yes it suits for everyone. Every scene counts and draw into my heart. I Loved how they act and show their emotions in their eyes it's so beautiful. Well at first i thought it's a long drama cause i saw a lot of BTS pictures on IG of the PD of this Special Drama until i saw some ending picture and i'm little bit curious about then i give it a shot and now i'm here loving it and definitely watch it again and again. I cannot compare this one to all other cause it's really really promising the actors/actress the plot. all i can say is bravo 10/10. for real i know i'm not the only one who really loves it. i laughed i cried and imagined that i was the one who's from the future and meeting someone to the past. well before i watch this i all ready knew who are the main characters and i'm really expecting for really good drama but they gave me a perfect year ending drama for 2015 for those who's confused to watch this. i'll tell you it's WORTH watching for so give it some try! your 2 Hours will be turned into years cause you'll go back the past LOL.
