I just started watching s2 (and I finished watching s1 like yesterday) and even if I only watched 6 episodes I know that first season will be always the best for me <3 Second is pretty nice, but I just don't feel the actors that much, and I miss Kang Dong Joo, Yoon Seo Jung and Do Im Beom, it is a little sad, that they didn't do a reunion in second season...
It's already in first episode, but then we have a quick break (if you can name it like that) and near end there is some too, but overall there is a lot of cute scenes
