How could Riley possibly resist a glittery, purple button?
Eyes bright with curiosity she looked at him quickly before just diving in and pressing it. She trusted he wouldn't have prepared anything bad. For a second nothing happened and she was confused, but that was fixed in the next second when the box exploded. And Riley shrieked in surprise.
It took another second for her to realize that the air was full of glitter around them and she wound up just laughing, letting go of his hand long enough to twirl. "It's beautiful!" Pausing to read the note inside, she just turned her smile on him, bright as anything. "Of course I'll go to prom with you!"
They weren't in the confused stage of their relationship where they had to ask, but it was so nice that he had.
