Maybe people did not enjoy it now but I remember watching this in my younger years and this was my first kdrama watched. I watched it on TV religiously, watching every episode despite of my class. I'm sure if you watched this back then you prob would enjoy it as well.
In the case of Dream High, I was suprised that Go Hye Mi started liking Song Sam Dong. At first, it was hard to accept that Go Hye Mi won't end up with Jin Guk but eventually accepted it. As for school 2015, I still think that Eun Bi should have ended together with Tae Kwang.
I'm going to miss everyone. T_T 54 episodes with them is not enough. After I completed this drama I rewatched the first half again or at least the first 10 episodes where I have not mastered which is which.
I remember having a dial up internet connection when at our home so I had to wait at least an hour to load the entire episode but I patiently waited. That's how much I loved the show!
