/cgl/ - Cosplay & EGL

Never had a crush but this happened very recently.
>Went to annual con in cosplay for the first time in my life
>Did the usual shit, karaoke and games
>Get to talk with way more people than usual however because of the cosplay
>Cool weekend all around
>Fast forward to today
>Friend contacts me saying he has something to show me on "Instagram" (got no phone, never browsed that shit)
>There's an account with the con's name that is basically about posting anonymous crushes to find back certain people
>Someone made a post mentioning me
>It's definitely a girl
Not sure whether to contact back or not basically. Even if I do I don't think I'll be able to keep regular exchanges, since I'm already not so much into social stuff.
