I enjoyed this drama a lot, but I had some issues with it. I first wanna clarify that this is a subjective review.
The thing I liked the most was the relationship between Yeo Joon and Soo Hyun is amazing and really beautiful. I recommend this drama mainly because of it.
I also gotta say that So Bin is lovely and I loved her, but I don't feel like her character added much to the story or she had that much of importance. However, the romance part was so delightful.
Another thing that I'm really thankful off, is that there is no triangle love, so I could breathe calmly this time.
The story is actually quite simple, in the sense that is something really common.
The music was AMAZING gotta say. I always moved my head with the music everytime the songs played, because they are such beautiful songs! I love how cute and lively they are.
The last thing I liked about it was the acting of Park Ji Hoon. Gosh, all the emotions he had to show and how well he portrayed them. I just am amazed of how amazingly he did!
So, in general, I think this is a one time watch drama and I really recommend it. It only has 12 episodes but I think the story didn't need more episodes, so it's perfect in that sense.
