Isn't it so cute when you're in high school, talking about how you'll be together forever?! It's a weird belief... you do believe what you're saying but you also know it's not really going to happen. Your forever is until college or until someone else takes your heart, hopefully before they meet someone else.
This kid apparently believes it's real and he proposed on prom night....
Man, he's really into this. He's in love. She might be in love.... but do you see the necessary excitement there?! She's holding a face for the camera, in my opinion.
There's another picture where maybe she's faking it a bit better :
