I finished this drama yesterday after only watching it for a week. It was good, but I think I got through it so quickly due to procrastination. It was fun to watch because I didn't know what would happen, but then again episodes 2-10 felt all the same, 11-13 were frustrating, 14 and 15 were better and 16 was good. I don't regret watching it, but I don't think it was the best drama i've seen. The story I really enjoyed. The concept is good, but as I previously said, it became repetitive. It felt well structured. You couldn't tell what the exact story line was, but you knew what he was going to do. You also never felt what the producers were intending, because you can tell whilst watching it that they need it to run for 16 episodes so it won't just be that easy. Saying that, there are points that are good. One major story point, don't watch if you do not like the thought of a teacher marrying a pupil. 'Coach' was their highschool coach, marrying a pupil. I didn't really like that concept (or the character but thats a different matter), so if I had known that was part of it I would have been put off a bit. I think overall, the acting and cast were good. Each suited their character very well. I think especially the main two characters. Not more can be said really, there wasn't a problem in that departement. The music suited the drama well. It wasn't a typical high school cheesy drama, so there was no catchy opening theme tune. However it has good tunes for different scenarios, which helps build the mood for the audience. It also incorporates the music quite nicely with singers and performers. As my boyfriend pointed out to me, they also clearly at some points used a microphone for live singing, which is nice! However, I don't think I would rewatch it. It is a sweet drama, but it became repetitive, and it got to the point for me where I thought I was watching to just find out, and once knowing the story line I didn't want more. It didn't have a particular spark for me and it didn't seem particularly sweet, just a bit frustrating. Overall, it was a good drama and I would say to give it a try, but its not amazing and it can get frustrating.
