Some time in May not too long ago, Su posted this link: https://www.fictionpress.com/u/980127/Airei-sama.
Her introduction, having included things such as her famous line, 'Wassup people!', being German, having lived with her gf of 4 years, and having 2 cats, it's safe to say that it was Su/Lin. (There are some things that don't add up, but really at this point we all know Su to be a compulsive liar. So whatever).
It's a huge coincidence that you just happen to have a very similar avatar (n same character) as the one she had in her blog.
I mean, seriously, if you're going to be lying again, you gotta try harder than that, Su.
