I was kinda iffy about watching school 2015 because I hadn't watched school 2013 but I went for it anyway. I have no regrets. This drama was VERY well done... the acting, music, setting, cast, EVERYTHING! I'm gonna have to say this one is on my list of favorites! And after watching 17-20 dramas so far, I only have 2 or 3 "favs." If you watch this I swear you won't regret it. You will cry and get pissed a lot but in the end it'll be worth it! PROMISE! (: (even though I was anxious so much watching this i'd probably watch this again low key!)
