/cgl/ - Cosplay & EGL

>Have friend who also cosplays and goes to cons from work
>She starts off kind of chill, we get along because we both like Kpop, Lolita, JRPGS and animus
>Go to a few cons together, everything goes great until the end of last year into this summer
>Start planning cosplays for cons in the upcoming year
>She chooses other characters from the same things, even though she refuses to play the games or watch the series because she "doesn't like reading"
>She plans a shitload of intricate cosplays, and has no skill to make them. I start getting floods of Skype messages and Texts that say "Unniee~ sew this for mee T_T we have to cosplay togetherrrr"
>One time I cave and go to her apartment to "Help her sew something"
>She sits on the couch watching TV and eating while I'm at her sewing table working
>Every time I see her at work, without fail, she calls me "unnie-chan" and speaks broken Korean at me.
>She lies to customers and our boss and tells them that she's Japanese-Korean and can speak the languages fluently when she's actually Chinese
>She constantly looks down her nose at me for wearing classic because she's a "Gosurori Hime-chan" but constantly shows up to meets in horrible Milanoo-tier Ita messes
>I've gotten to the point where I moved my shifts around so that I avoid her

The worst thing about all this is that both her boyfriend and brother are cosplayers too. I've even suggested that she take sewing lessons or at least let one of us teach her the basics, but she says she "can't understand or remember anything". She doesn't even talk to her boyfriend anymore because she's always following me around.

At first, she had little habits that made me question her, but with this and other things she's done, she has evolved into a full-fledged horror story.
