Will I be able to build good friendship with another otaku?

Depends on how Ты act on it...I dunno If I should answer this since I'm also a bit socially-akward (and by that I mean I always keep people in between: not too close,not too distant ^^"...)but Ты know...do a private cosplay show,play some Аниме related games,watch Аниме together...y'know,those kinds of stuff. Haha...I'm giving bad advice, but seriously though, just let time do its course. Ты already found some common ground so make that a conversation topic from time to time (not always because it would become kinda pushy)and if Ты really are committed then,I'm sure your efforts will be rewarded.

I know exactly how Ты feel,and quite frankly,I suck since I don't even do much about it,but when I do,my confidence in socializing and stuff gets a tiny bit higher...It's like letting bottled up feelings out because then you'll realize that Ты have the inner blabbermouth inside of you. ^^"

The same thing also happened with me . I met a girl who was an otaku like me And didn't know how to become her friend. But we started talking hours about Аниме and Аниме related stuff. We also started watching Аниме together. Now we are best friends! Ты can talk with her about Аниме and the characters. Ты can give her some gifts with a picture of her favourite character(I did it,once.) или buy some Аниме dvds for her. invite her over your house to watch anime. start Пение Аниме theme songs together :) me and my friend keep doing this all the time.
