What an amazing drama this is.
I like yanki stories so I started watching this thinking it would be just a stupid yanki story like in Kyou kara ore wa, however from the first episode I could see there was way more than just a side story to binge watch.
If you are looking for something miningful with stupid and serious characters at the same time, this is your best chance. It is also only 10 episodes but it totally feels like there is more, I became fully immerged in the story, i felt like I was watching it from inside. I was not expecting to enjoy this as much as I did.
