No happy ending for this cringeworthy marriage proposal

A boyfriend staged a cringe-worthy proposal in front of a baseball stadium—and the whole thing was so awkward some viewers believe it has to be a hoax.
Footage of the ill-fated moment surfaced on Instagram earlier this week. Four men, presumably friends of the boyfriend, can be seen performing a short choreography to Bruno Mars' Marry You at the Columbia Fireflies' home ballpark in South Carolina.
Once the men are done dancing on the field, the camera pans to a couple in the bleachers. The boyfriend, naturally, gets down on one knee and presents his girlfriend with an engagement ring in a box.
But as soon as the couple appears on camera, something seems off.
The girlfriend, instead of looking overcome with emotion, is shaking her head no. Her boyfriend seems to ignore this warning sign and goes through with the proposal.
Things don't get better for him from then on, with his partner giving clear sign this is not what she wants.
She eventually raises her hands and recoils. Then, the woman can be seen whispering something into the man's ear.
The boyfriend, meanwhile, looks a bit surprised, with his mouth open in a mild look of horror.
