Samford captured their special moment on video and it's gone viral with more than 1.5 million views.
Pierre says he'd been planning the moment for weeks, but he's known from the very start that she was the one.
"I told my friend, like 'that's going to be my wife one day, that's going to be my wife.' Not even really knowing her as much, just seeing her. And then when I got to meet her and got to know her personality, she's the greatest person I know, besides my mom," Pierre said.
Pierre says it will be a long engagement. The two are juniors in college and want to wait until after graduation.
