I know this is an old thread and I probably shouldn't bump this but I have to say this.
I am/was exactly like Densha was. This was of course before the TV show however. I am/was a huge Otaku who had a ton of Anime, Games, and Toys, My room was like his room when I was 24 (I'm 31 now).
I always had a problem talking to girls because I was shy and feared rejection. I was always turned down by girls when I was in school and I was picked on all the time and got in a ton of fights. Not for being an Otaku but because I was a small kid and henceforth and easy target. But I digress.
I managed to somehow work up the stones to put out an on-line personal ad back when things like Match.com where new and more importantly completely free. I got a few replies but one girl kept replying to me and we E-mailed a lot. Then came the faithful day we met and yes he was exactly like “Hermes”. She was beautiful, refined, and just a very sweet person. I then because nervous because I knew at some point I would have to take her back to my place. And that she would see my wall scrolls, my anime toys on the bookshelf, the bookshelves full of anime and manga, the CD rack full of video games and all the game systems I had hooked to my TV.
I was scared that I would lose what was becoming the best relationship in my life however I also knew that I could/should not hide who and what I am/was. Needless to say she was a bit well… Shocked when she saw my room. I saw this and my heart sunk. So I just came out with it. “Umm I know my room is a bit much” she just looked back and said “I think it’s nice” and things went well from there. I wound up taking her to her first con later that year and she loved it. We got married a year later and we have been married ever since then (going on about 6 years now).
The thing is be who you are, Otaku or otherwise. If someone likes you they will stay by you no matter what (unless you are into illegal things that is) just be natural.
The funny thing is we started watching Densha Otoko and we are just finished Episode 8. My wife loves the show because “They are both like us”. So I see no reason for anyone not to derive inspiration from it. Is it a Bible to live by? Not quite. Is there some inspiration to be gathered from it? Yes there is.
