Great cope material for women.
Seriously though, even if she didn't turn him down, which she might have done only for an ego boost, think about the relationship dynamic that they would have.
The guy is dating a bald girl, and unless he's a complete moron, he would realize sooner or later, no matter how sweet she is, that he's doing her a huge favor and that he holds most of the power in that relationship.
Think about the first difficulties they'll encounter in their relationship, the guy would most likely think at a point, "Gee I'm with her and she has no hair like almost any other woman, what an ungrateful brat!"
That's what I hated the most about the relationships I had before my hair transplant.
Sure I was sweet, funny, tall, I was a nice face but. But. The girl was still dating a bald guy while 99% of the guys my age out there had a full head of hair. I was deficient, and they knew it, any mistake I would make, they'd become bitchy and started hating me because they felt like they had settled for someone who clearly is "less than", no matter how you look at it.
That's how a guy dating a bald girl will feel at a point or another. Yes, it's terrible but it's human, and there's nothing you can do about it.
Besides, no one should take YouTube videos like these too seriously, 9 times out of 10, they're staged and designed to shock and to pretend that reality is not as we think it is.
"Look! That bald woman should be rejected by that man, but the opposite happens!" Come on now, great exception, great actors, but we all know what happens in 99% of cases.
