This is an amazing show, I loved the story line, even though I definitely do have second lead syndrome, I understood each of the characters motivations. At times the story does become diluted, they tried to add a lot of plot to fill each hour long episode, and while the scenes are shot wonderfully there are some inconsistencies with hair or with props and things like that, small things most people don't pick up on. Overall, I encourage you to watch this movie, it deals with serious topics in a very smart way, and it shows you the dark and light times we all have in high school. All of the acting was brilliant, when they laughed, I did, when they cried... Not gonna lie, I most definitely sobbed, specifically with Yook Sung Jae's character. I feel like in some parts of the story, there were things that were added but never fully explained, however I was happy with the ending and the message it said in the end. To reach out to anyone if you see them hurting and tell them "it's okay to hurt." Of course there was romance, suspense and mystery, but the core of the story was just that, that it's okay not everything is okay and that you have to keep your head up, don't let anyone knock you down. Anyways, if you've made it this long through my review, thanks. And really, really, watch it.
