It was a “perfect” night indeed.

One Nevada high school student was recently surprised to be crowned prom king at the big dance, and the moment was captured in video footage that's touching hearts across the internet.

In recent days, a clip of the sweet scene hit Facebook, where it has since gone viral with over 46,000 views. According to Fox 13, the teenager in the video, Edgar, was surprised to be awarded the coveted crown on prom night, after a classmate named Shaun “stepped down from the honor” and requested that Edgar, who has autism, take the title instead.

In the footage, a school official announces Edgar’s name as king of the dance over the loudspeaker in the festive venue – and the crowd erupts in cheers.

“Edgar! Edgar! Edgar! Edgar!” the students chant and shout in support.

The prom king is all smiles as he accepts the crown and shares a hug with the official, touching his new royal headgear in apparent disbelief. Soon, he was tearing up in response to the overwhelmingly happy moment.

Minutes later, Edgar hit the dance floor with a student who appeared to be the prom queen, sashaying and swaying to Ed Sheeran's “Perfect” — a serendipitous tune for the special moment — before the rest of the prom-goers join in.
