This is a show I recommend to everybody. It's got everything you could want and more. I'll admit that it isn't the most mature/serious show in some parts, however I think that's just how Gong Yoo works; he's just got a knack for that kind of character. I was seriously absorbed into this show, and I didn't even want to skip the parts with the secondary leads (Lee Dong Wook and Yoo In Na) because they were so good too, they all had such chemistry. The bromance was super fun to watch too. I just find myself coming back and then laughing or crying. IT IS SUPER SAD! You have been warned. I must also note that the music was fantastic and really stays stuck in your head, even now I can hear a song from the show playing in my head. You will want to look up the soundtrack after you've seen it and keep it somewhere safe.
