A story which focused on ouroboros - the symbol of infinity through a snake chasing its own tail. Representing creation and destruction; birth and death.

I really enjoyed the symbol of the ouroboros in this drama, along with everything else this drama had to offer. It was thrilling, but also funny. It's a compelling drama following two friends - a police officer and yakuza - carrying out revenge for a person who was their family as a child. You couldn't help but love both the main characters. And of course, they made an amazing team when they had the chance to work together (undercover, of course), and they were quite an hilarious duo during these times.

Speaking of, both Oguri Shun and Ikuta Toma played their characters fantastically. It was definitely fun to seem them reunited on-screen after Hanazakari no Kimitachi e which was released in 2007. In that time they had obviously both matured as actors and their portrayals of their characters felt authentic and genuine in this drama which is a lot more serious than Hana Kimi. It was very obvious to see how much they cared for each other. Shun's character (Danno Tatsuya) treated Toma's character (Ryuuzaki Ikuo) like his younger brother whom he wanted to protect. And it was obvious Ikuo equally cared for him. It was really sweet but also sad during the times Tatsuya would get hurt because of how worried Ikuo would get. I also loved the contribution Ikuo's sense of smell would make. A pretty funny quirk.

I know some people were annoyed at the female lead, but she wasn't bad in my opinion. It's important to know that for the most part, she didn't know about Tatsuya and Ikuo's relationship for the most part. So, whilst I sometimes felt like she was getting in the way, she was doing what most people would do in that situation, especially as a police officer herself.

I also really liked how the other side characters contributed to the story. also, Ayana Go was also a character in the last few episodes and I was not expecting to see him, but it was nice to see him in this.

I find the plot quite hard to fault. Revenge is quite a popular troupe and this drama made it into my favourite revenge plot dramas. There were a few red herrings but I also felt the emotions Tatsuya and Ikuo would feel when they thought they were getting somewhere with a certain suspect.

I also found the ending fitting. That's all I will mention on that. I was pretty sad, but also relieved in a way.

Overall, a great drama which I definitely recommend for all the reasons mentioned above. It has easily become a new favourite of mine.
