I really liked the first couple chemistry and I feel like it wasn't the best idea to separate the 2 stories, because you'll inevitably compare the 2. And if you really liked the first couple, having them almost completely disappear, it can be hard to stay interested in the second storyline. And even tho the second couple was quite decent, in comparison to the first one it was a bit disappointing. They all did a great job considering they aren't veteran actors, but acting and chemistry wise boosnoeul were largely on top. It's too bad cause at first I really liked this series, even with some scene with really bad production and the problematic part of it ( I admit all my favorites series are a bit problematic, because I like the realistic side of it, love can be problematic and it's a reality for me, no relationship is perfect and flawless) but in the end it was hard to keep my interest up. It was still enjoyable, especially payurain arc.
