Wow...Just wow. I never knew what was coming next. Okay so the romance between the main girl and the guy from the past is only seen in flashbacks but it's so realistic and so pure and innocent, I loved watching every interaction they had. The acting was top tier and the storyline kept you guessing till the end. I love the duo of the 2 main leads, I love the friendship and the trust that they built. I hated the villian more than Ive hated any kdrama villian so far.It was Fantastic...That being said the reason this drama did not recieve a 10 star from me was because of the ending. Now I have learned in the Kdrama world, a common downfall many of them are unsatisfactory endings. This one was unfortunately no different. The ending was not horrible by any means, it just didn't tye it up in a nice full circle bow like a wanted. I really could've done with one final scene where the couple we'd been watching and feeling sorry for could've seen eachother. Besides that it was great ?
