Spoilers ahead:
I'm so sad that this drama ended! I loved it, not every single moment of it but most of the episodes were pretty damn good, I enjoyed the plot and even if I'm sad that they didn't end up as a band together I was glad that everyone pursued their own dreams. It's been a while since a drama made me cry (or stay up till 2AM just to finish up the latest episode) but the ending of 14 and 15 (in my opinion) were so sad (or the background music made them so) that I had to blow my nose every 5 minutes. I think that the Do Il/ Stalker chick (will never remember her name) relationship needed a little bit more attention and also I did not see enough of Kyung Jung and Ha Jin (to the point that I just had to google Shut Up Flower Boy Band to check their names out). But altogether this has turned out to be one of my favorites and I'll miss it a lot
