<p>This is definitely fanart, then. The person who made this made an AU where Hermione married Draco and had three kids with them, and then Scorpius married Lily Jr.</p>
<p>It's not confirmed who Scorpius, Lily, or Rose married. All that is known is that Scorpius had a crush on Rose when he was fourteen (even though Rose was a total jerk to both him and his best friend).</p>
<p>^ Yeah man, as far as we know it's an AU because it's not confirmed who any of the students in Next-Gen end up with. Besides, it's probably a better idea not to put much trust in things that aren't explicitly stated in the books/movies, here, or Pottermore because they might not have the correct information</p>
That's not actually true, though - canonically speaking, Hermione ended up with Ron, and Rose doesn't really have a love interest unless you count Cursed Child as canon
