This was such a Heart wrenching drama. It made me cry even when they were still young until they grew up. The cast are perfect, Hyekyo is very natural when she acts and ChaeYoung here really made me hate her but that's what made this drama even more outstanding. Cast are so outstanding in my opinion, but if you ask why it's nine in the Rewatch value, I haven't watched it again because it was too sad to watch, that would make me cry and hate more. The music is very affectionate, may be sad or not, the singers and instruments are awesome. The story itself is very eye-catching,I love it! Perfect. I totally recommend this. There was no episode where I didn't cry.
