Reth wasn’t happy about how Marina had left him that afternoon, just to go back to the other prince. He kept trying to rationalize, to fight his feelings, but in the end he couldn’t shake the uneasy sensation off of him, and he was getting even more impatient to see the queen again. He wanted to forget those feelings, and the only way he had was to fuck until both he and the queen were spent. Seeing how Marina hadn't come back to him, he decided then he could easily go to her instead: being hand of the queen, after all, had its advantages, and nobody would doubt of his good intentions if he went in the queen's chambers at such late hour.
When he started walking toward Marina's chamber, he had all the intention to spend the next hours making her howl in pleasure, but with every step he made toward her chambers his first idea started to waver: he knew she was promised to another one, he had known for quite some time and had decided to ignore it, but the more he ignored it the more his weird attraction to Marina grew. He knew from the very beginning what he was doing was quite wrong, mixing sex and politics was never a good idea, and now... now it was time to stop, before it would go any further.
Once he had been accompanied from a servant in Marina's room and once they had been left alone, he gave Marina a little unhappy smile before he quietly spoke "I think that from now on we go back to a work relationship only."
