Well done show. I really enjoyed it. "Longing Heart" was sweet, cute and innocent time-travel drama. It made me think about the future and how my choices can affect it. Even though is not the best drama I've seen, it was a nice to go back to 2007 were Girl's Generation was just getting started and flip phones were a thing.

Acting / Cast: The actors did well, this isn't an acting masterpiece but it was good. Lee Jung-Shin was the person that stood out the most for me, I really liked his acting and how he portrayed adult Shin-Woo with is the mix between a very adult person who still had something of a child inside. Seo Ji-Hoon also did a great job even though the writers sometimes made his character look like a little kid even though he was almost eighteen. Lee Yeol-Eum was also good, but I found her character a bit lame and annoying at times, but I think that was more about the writing than about the acting. The rest of the cast was also very good and did great supporting the main cast!
