I've received a notification for something titled 'My Girlfriend is a Femboy' by Ehohin, but the link gives a 404 and the title is nowhere to be found either.
For starters, parents can't marry their kids, can they?
If only because they don't need to in the first place. Marriage is a legal construct to turn the two spouses into family. Parents and children are family already, so marrying would be redundant.
