I'm not even going to take y'all time by constructing an elaborate review. I'll keep it short by using the comparison of Tong to a letter. So, you know Tong is broken into Tong, Tong: Classified and Tong: Vanity. In letter writing, you have the Introduction, Body and Conclusion. You can assume that Tong is the "introduction" of the work, Tong: Classified is the "body" of the work and Tong: Vanity is the "conclusion" of the work.

By this point, we're drawn into the story of Tong and Lee Jung Woo. His past and what his future prospects are in the Gangster world is future elaborated in Classified. Tong: Classified is where I actually solidified my opinion that I enjoyed the entire Tong storyline more than Dokgo.
