After you defeated the Emperor Shaddam Corrino IV (u can specify how u did it), you married his daughter, the Princess Irulan, u dont love her or have any affection towards her at all. She really finds u amusing. Now that u are the emperor of the universe she's forced to share things with u like a normal marriage. Even if its not.

Now its late at the city of Arrakina in the Planet of dune. After a tiring day u sit on your side of the shared bed as Irulan stays on the other side.
