It's a show airing in Japan right now about a complete loser otaku who saves a drop-dead gorgeous rich girl from a drunk pervert on a train. Since he knows nothing about the opposite sex, he posts about the incident in a thread on a popular Japanese message board, getting tips on what to do to get the girl, basically.

The show is very unique because it contains lots of extremely accurate references to geek and otaku culture, managing to pull off 15 minute scenes consisting only of him posting on the message board and receiving replies that don't get boring in the slightest. It's hilarious and heartwarming, definitely the best live-action J-drama I've ever seen.

If you haven't seen it, don't wait any longer. You're already really missing out.
