I liked this anime, but I recommend everyone to watch the Korean Drama before watching. This anime summarized the plot using overall 30 mins when the Korean Drama is 16 episodes so it might be hard to see/understand what is going on. It indeed skipped a lot of scenes from the original. It has a lot of sadness and overall great music in the story and in the credits. The art is nice so are the characters (if you understand the plot). If you like short anime like this or a shorter story instead of the Korean Drama I do recommend you watching it. Especiallysince Korean anime are so rare.
