I think the title of that story is, I’m a Villainous Daughter, so I’m going to keep the last Boss.
Where she went to the Demon King, to get married to him, just so she could live....
That's the one I think. Reading this makes me want to read that manga.. thank you do much ლ(´ڡ`ლ)
I know it's off topic, but there's a manga similar to this. Instead of a Dragon it was Demon Lord in his castle... I forgot the name of it ┗( T﹏T )┛
