This drama was really good especially when sejeong is in it! I love her acting! She has improved from school 2017 by a mile and we are happy to see her improve in it! The other charcters were really good as well! although their are some parts that were dragy but I woudl still give this a 10 cause I like music and mystry dramas and this drama is mixed with both Myster and Music ao that's why I love it so much!

Sejeong showed her potential in school 2017 and now she has prove again that she has the potential and capabilities of being a good actress not only a singer but an actress! she has always been hardworking ever since! we hope that in her new drama this 2020 it will be an even better and more widly impact than this becuase this drama was good but some people doesn't like it so I hope the drama that Sejeong will enter will give her the recognition that she deserves as a hard working and determined person.
