After three years of marriage Tonraq thought he would become more used to Senna. When he gazed into her bright blues eyes he still couldn't help but go numb, yet he felt so secure with her near. She was the love of his life and he didn't want to withhold anything from her. He did his best to give her everything that she needed. He gave her everything that he had completely, but there was one thing he could not give her. A child.
He watches her as she gazes out of the window and into the night sky. He wants to say something to her, but what? He lifts a warm hand intending to embrace her but something stops him. Guilt overwhelms him. The same guilt that was starting to slowly separate them.
It felt childish, Senna had not done this for many years.
"If you ask Yue and be patience she'll give it to you." That's what her mother had always told her. It was naïve of her to think this would work but she felt hopeless, she didn't know what else to do. She felt as though something was missing, but how can you lose something you never had? Tonraq was an amazing man an even better husband he did every thing for her and she couldn't even give him the one thing he had always wanted. To be a father. She felt his presence creep upon her but she didn't turn around and she said nothing. She couldn't even bear to look at him. She simply stood there sending her silent request once again to the moon spirit.
How was that? I mean it was just a rough headcanon of mine. Not sure If I'm going to add on to it or not, but if you have any idea's please share them.
