Train Man 2: Densha Otoko

A real-life thread on an internet forum started it all. A nerdy otaku meets a girl on a train and posts an urgent query on the web--How the heck do you talk to girls? What should he wear on the date? Where should they go? The forums response was amazing and the thread grew incrementally longer as the nerds relationship with the woman developed. Eventually published in book format to become a best seller the thread spawned a blockbuster movie a hit TV series as well as this heartwarming manga adaptation of an entire internet community rooting for love and romance.
