Absolutely LOVED this drama, everyone's acting was perfect, especially Seo In Guk, he was the star of the show, his acting improves with each drama, I think he is one of the best actors in Korea at the moment. This drama is my favourite kdrama of the year. I watched this drama when it actually started airing on tv, and I think this is the only drama that I watched from start to finish that I enjoyed every single episode of. At first I thought the storyline was a bit dumb, I mean how can a 26 year old play an 18 year old, and I had not heard of the other actors in the show, so I was expecting much. I think the writer, director and all actors did an awesome job, the drama had the perfect ending. Would definitely watch again, actually I've already watched it twice haha. Would definitely recommend it to anyone looking for a fun, sweet drama with awesome acting and a great storyline and ending.
