One commentor expressed skepticism with no proof and then a person responded to them with an article about this couple talking about how they met. So yes, there is pretty concrete evidence this is real
Which one are you talking about? Because none of them feature concrete proof if you read them. ‘Doesn’t mean for sure’ isn’t concrete and also if it is correct it does not give us the answer to is she happy or not. And slight speculations do not count.
Read the article it is right there. That is concrete proof. It announces their engagement and explicitly says where they met. I don’t understand how this is ambiguous to you.
