Mother // Yandere Stepson x reader

⚜Chapter 5⚜

Y/n wore a beautiful gown that made her and her body stand out even more. Thanks to someone, she had to wear a high neck and long sleeve dress to hide the love marks on her. Apart from the fact that she was dying from the heat, she looked exactly like a beautiful young bride. Looking at her, Castian couldn't help but wonder how delightful it would feel to be wed to her. This thought took him a bit by surprise, they knew each other only for a week, it wasn't rational at all. Just like her family, she seemed to have something in her that could charm anyone. For the first time in a while, he started to wonder where will she go once she divorce his father or when that old man died. If she doesn't have a child in the most normal case, she would return to her family and remarry after some time. But could she remarry? She is a duchess and the obvious way both of them flirted with each other would definitely hurt her reputation. He couldn't help but smile, she would never be able to remarry unless HE marries her. Or was it that she wasn't going to remarry? He heard how some women preferred to stay single or to never remarry. After all, she would be free to do whatever she wanted afterwards. This idea didn't please him AT ALL.

Not that he minds her begin free, but in his heart, she was already his. He didn't want her to stray too far from him. Should he make sure that she becomes pregnant? Even so, the child would be legally his brother. He wouldn't be able to touch her as he did after his father's death. Now that he thinks about it, who said she wasn't already with his child? He must think of a solution and fast. But then again the idea of her belly swelling with his blood was quite appealing. 

_Castian? Is everything alright? 

_It's nothing, I'm alright my dear... mother.

Y/n frowned at his silence before calling her mother. She did notice his changing expression too, at first, it was a soft and fond smile that could make any woman's heart beat faster. Then he frowned like something was troubling him before letting a small laugh. It... was a bit creepy seeing all unravel before her. Whatever was on his mind was important enough for him to change his expression every minute. 

_Are you sure? 

_Of course, is there a problem? 

_You seemed worried, then you laughed. 

Castian looked at her surprised before smiling. Maybe he wasn't that different from his father. No, he is different. Unlike the old man, he wouldn't wait for her. He would take her with her consent or not. The problem, no one knew what she would do after her divorce or his father death. If she wished to leave the country he wasn't sure he could stop her. She wasn't the smartest, but she wasn't the dumbest too. Castian isn't blind he knows she is not in love with him, in fact, she was doing it only to make his father suffer AND divorce her. Thankfully his old man's obsession for Beatrice Monet was stronger than that. To the point where he could endure this humiliation just to keep her "substitute" called Y/n, the granddaughter of the woman who haunted his poor mother all her life. His mother would have cried if she knew the feeling her son was harbouring for her "rival"'s grandkid. 

_I see, please don't worry about it. 

Now that he thinks about it, his cousin, the actual emperor did ask him what he wanted as a reward (aside from the gold and many other things he got along with the reward). But since he didn't know what he wanted, this reward was put on hold. And if he didn't have the power to change her marriage by himself, a ruler could do it more or less easily.
