This drama could look like a melo, but it isn't. It could have the most predictable plot, but it doesn't. This is everything but what it looks like! This is why it is worth watching. This is more of a romantic comedy with melodrama aspects rather than a real melo. It has a lot of funny moments and characters, and a lot of plot twists. The story was nothing new but just when you think things got better or worse, something else happens, but it doesn't turn out like you imagined. The writer was very good at overturning situations and destroy old kdrama cliques we were fed up to roll our eyes at. It literally happened the unpredictable, and this is what makes a kdrama enjoyable. The main couple had a lot of adorable moments that made me like them a lot. If you like romcoms, this has a few RC moments and believe me, even if you don't like heart transplant dramas, this is nothing like usual. Everything about it is addressed and given an explanation. The cast is excellent. I loved both leads and the secondary characters. Jung Kyung Ho was awesome as Kang Min Ho and he shifted from a heartess man to an eccentric and cute teddy bear in the span of a few episodes. His character will definitely be one of my favorites ever. Kim So Yeon played an 'iron lady' character, which is her best kind of role. She was very good at it and her chemistry with the male lead was spot on. The second male lead Yoon Hyun Min also had a surprising role of an evil man with greed. It really looked like he hated the male lead, when truthfully they are best friends in real life! Literally one of the few evil characters who did anything to get his way, somehow I applaud him because of his desperation. I loved the music as well. The main theme Paradise by Davink caught me at the first listen and I still listen to the OST now. I would definitely rewatch this several times, so you should watch it too! I assure you won't lose your time. :)
