Story-----Okay so i was very suprised that this drama got me hooked at the very first episode!For me it doesn't happend often so i was so so happy that this happend after such a long time!I give the writer a big applause because he/she did amazing job!The story was well thought and everything went together like puzzle!The mystery and romance and all together was amazing..I was also happy that there wasn't any big romance triangle since that wasn't the 'drama' in this series!You know i hate love triangles so i was glad i didn't saw that here!I love the ending the most because not lot of k-dramas show us how the character's developed in future but this...aahah it melt my heart and i was jumping up and down from the cuteness! Acting----This was absolutely amazing for me..Lee Hong Ki already had role in acting in past but finally he got main role!I was so so dissapointed when i saw him as Jeremy in You're becautiful because for me they didn't show his acting talent!The chemistry in this drama was so crazilly amazing that i was watching it with open mouth!Don't argue with me i think i'm right!If not i wouldn't be even writing this!^_^ Music----The music was awesome and it just fit so much in the scenes that i had to download whole OST album to my phone and i listen it till now! Rewatch value----I already rewatched it so many times!It just so amazing and sweet that u can't stop!I love pure love and true love and this show proved it to me!So i give 10/10!You should rewatch it lot of time so you will never forget it!You can also learn from their story!
