For me, this is a drama that's hard to review because my opinion changed so drastically over the episodes. The first 10 episodes were amazing and I couldn't stop watching. They were funny, entertaining, dramatic and sad at the exact right time. The writing was incredible and I loved all of it. The second half of the drama disappointed me a lot, though. The story started dragging and it felt like they could have easily put what was left of the plot into 5 episodes instead of 10. Things started to get repeated and the characters' actions frustrated me, episodes went by without much happening and I had to fight my way through them at times. Still, I overall really liked the story. I think it was more a pace-problem than a story-problem. The acting was phenomenal. The main actors did an amazing job acting two roles at once, everything seemed natural and I really felt like they were in character the whole time. The characters themselves were interesting, entertaining and nice to watch. I liked the side characters, too. (Except for the second half of the drama where they got really, really clicheed.) The music was nice and fitting, the scenes were beautiful and I'll definitely rewatch parts of this drama, too. After watching the second half, I actually didn't want to rate this better than 8, but thinking back to the first half of the Drama I would've rated it a perfect 10, so combining them I'll just take the middle-way.
