Love the story concept of this series. Watching how the professors neglected to properly guide their students just taught me how to be a better piano teacher myself. The casts were so into music too. I am so convinced they were musicians themselves - making this series even more believable. What's really heartbreaking for me was when Song-ah's love for violin ( same with Dong-yoon and some other characters ) faded in time despite proving to everyone that perseverance and hard work can make a struggling violin student play like a pro, that music is not only for the talented.
