Its gotten so popular out of nowhere and I assume its because of its great cast but this kdrama was such a drag and bore throughout most of the episodes. I guess you really have to love these characters to enjoy most of its episodes but I just couldn't bring myself to find anything interesting. I do admit though that at the end of the episodes like the last few episodes roped me in and I really enjoyed it! So I guess I enjoyed their adult years more than when their story spoke about their teen years which was most of the show...I also found the main characters' relationship weird mostly because of when they met she was underage and he was older. I think those two would've remained best if they always stayed as friends and I'm glad they didn't end up together in the end because there was simply no chemistry between them, in my opinion.
