I absolutely love this drama, the storyline, the acting the music it just a well put together drama in my opinion. Some may, however, disagree saying that the storyline is a bit repetitive and mostly really stressful and annoying. But to be honest it is not if you see the characters' goals and their mindset. Walk-in their shoes and you will understand why the storyline works. As for being really stressed, yep, it is there isn't a lot of happy moments or cute/sweet moments as it is usually ruined. The good character receiving the worst punishment possible and being treated unfairly, while the baddies seem to get away with everything. You just have to watch to see what happens. At times it will become difficult to watch because you may feel bad or scared or straight up sick. Although, it may not seem like a good drama, well, I never got bored watching it, sitting on the edge of the couch waiting for what going to happen next, heart beating fast and stress, it like being on a rollercoaster it may seem scary and no ones want to go on it but people still do and it the end it really fun just like this drama

The song and the music - I love the song, that is it really there no explanation you either love it or hate it or love-hate relationship. just like all music.

The rewatch value, the reason I gave it a 7 is that, like every TV show or dramas or movies, it could get pretty boring for some people, but personally I think that this drama has a deeper meaning like comparing and contrasting between relationships like mother-daughter, father-daughter, sister-sister, and lover. Understanding why a character might act a certain way, what is their life like to make them who they are. These questions may not entirely answer the first time watching it but after the second time you may end up feeling bad for the baddies instead of hating them you never know.

So why 10/10 - simple, the acting was amazing, the storyline is really great, the music oh my god love it and the production and cast so good.
