Be REALLYYY careful, dude. Especially since you're only 15. I'm glad parents will be there so you can at least make sure this isn't a creep or a 45 year old man coming to kidnap you.
And do make sure she wants to video call and doesn't act like she's hiding something. I got groomed(?) by a 33-year-old man who sent pictures of a teen boy and said it was him, so there's that. Then he blamed me for it and said I guilt-tripped him into dating me and groomed HIM.
Stay safe.
