Wow. A nice drama. I really enjoyed the unique plot. The actors were great. The OSTs are awesome. If this is in your watchlist, don't delay watching this drama.
This drama is a good one. Actually I was fed up with rom come. But this one was good. Some scenes are cliché. But this drama is just sweet and light hearted. Loved it. You can just entertainment yourself with comedy.
This is a slow burner thriller but OMG what a show! I'm just very impressed by all the actor young and old, they…
Don't you think the drama is kinda similar to sky castle? Of coarse there's Kim Seo Hyung. And there are students' murders/murder attempts. A problem with illegal exam papers. Suspecting students for murders. Paternal problems. And students suffering due to adults.
Honestly I thought the drama would be boring while watching halfway through the first episode. But at the end of first episode the drama managed to hook me to it. Everything else is history. Love this drama. Actually this drama's ratings have sky rocketed from EP 1 to EP 20. From 1% something to 23% something.
The tutor was the best villain. I'm gonna rewatch NOBODY KNOWS. Kim Seo Hyung's evilness is on next level. I'm gonna watch her in a nicer heroic role in Nobody knows. Sky castle is on whole another level.
Wow. That was an emotional rollercoaster. I'm lost for words. 10/10 rating. This drama is a real gem. The acting is so great. The story is top notch. Definitely one of the best kdramas I have ever watched.
Wow this drama was so amazing. The action scenes are crazy. This is one of the finest action dramas I have ever watched. This is a must watch for every action lover.
But the only problem. There's no ending. The drama "ended" with a beginning. So at the end you will be desperately waiting for the season 2. That's a given. So if you are not a fan of waiting for an end. This is not for you. But you will definitely be miss out the amazing action and the story.
Korean makes great drama. As international fans, we know Historical dramas aren't about history but about DRAMA. After all, we are not watching dramas to learn any Korean history. It's all about entertainment. It's simple as that. They show a display of disclosure regarding that matter. And no one believes this is real history or anything. After all, this is not a history lesson. So there's no need to fuss about that you Knetizens. After all, how can you believe all the DRAMA they show on typical Saeguk drama was true or "seems to be true"? Just leave these amazing people alone.
