I think this show is overrated, due to the good and famous OSTs' and actors, but the story is a little empty for it to be as famous as it is. The main leads look strange together due to the large age difference, even though their chemistry makes up for it. Gong Yoo still has more chemistry with both Dong Wook and Sung Jae than Go Eun. I think I enjoyed In Na's and Dong Wook's relationship more, because they were more age appropriate and also, because they had more history and chemistry together. I would've enjoyed them as the main couple more than the actual one.
