[Based of IRL]

Your old best friend had taken pictures and videos of you without your permission when you said that you're not comfortable with it. Then they even sent them to strangers online. Ever since then you've struggled with taking pictures or videos of yourself, especially when someone says "it's 'just' for memories"

You and your 4 boy best friends were hanging out at home, doing nothing special.

Sam: Omg, let's take a group pic, guys!

Alex, Jim and Ethan: Sure?
