There's nothing to help other bernds, all I can say is go outside maybe and it could work out.
That's pretty much how it happened to me, I didn't do anything special in order to get gf other than just be myself and be outside.
I will say, though, that the fact that she likes me should be proof that any other Bernd that isn't myself should be fully capable of doing the exact same thing I do, considering the fact that I've sunk my entire life into an imageboard and lost all personality in the process.
The more I talk to her, the more I start to realize that she doesn't even really like me as a person, but she likes Bernd. The only difference there might be to lower or increase the chances are the way you look, and I wouldn't say I look exactly great or anything, so other Bernds should be able to do the same as me.
