I love this drama for several reasons and I'll tell you each of the reason why you should need to add this on your watchlist.

1. Very deep meaning using relatable situations for almost everyone. One of the things I really commend about this series is the fact that they used common scenarios that can be understood easily. They also didn't add a lot of law technicalities so even if law genre doesn't interest you or you don't know anything about law, you can still enjoy it.
2. The colorful characters. In most dramas we identify who's the main leads and who are the villains however in Juvenile Justice, it's difficult to draw a line. Everyone has a fair share of good and bad in them that it's really hard to tell whether they're a good or bad person. Personally, I can't stop myself loving all the characters.
3. The actors and actresses. Of course, this series won't be successful without the casts outstanding portrayal. Kim HyeSoo did not disappoint and she perfectly embodied a judge who is strict and serious but at the same time uses logic and compassion to teach the juvenile offenders a lesson. Her portrayal is certainly outstanding. On the other hand, Kim MuYeol, another actor who's known for versatility. His character here is a lot more passive than the previous shows/movies I've seen which is why I'm a bit sad. His portrayal as an associate judge who's very emotional and show empathy to all the juveniles is on point but I guess his character as Judge Cha TaeMu is a bit plain. Compared to Judge Shim's character, who's very fierce and aggressive, Judge Cha's saint-like personality has been outshined by Judge Shim's unique way of handling her cases.

Actually there's a lot more to expect from this series and it's definitely worth the watch. I hope you try watching this and fall in love with its heart-wrenching show filled with a lot of lifelong lessons.
