Whenever I see things like this I feel like it's really inappropriate and puts a LOT of pressure on the girl to say yes.
But assuming that she actually wanted to say yes, congratulations to them both
No I'm with you... if the one being proposed to is having doubts about it and something like this happens, they're basically forced to say yes or else they're the biggest piece of shit on the planet. I'm not into it. In this case in particular, it seems like she said yes, so more power to them.
