The war is over and Sanemi tries to make a life for himself, but soon he realizes that something in him calls to the dark and he is becoming lost. He reaches out to Giyuu, despite the fact that they have never been friends. Maybe it is because they fought the same battles and lost the same people. Or maybe it’s because they are both on a very short list of people who share the same curse.

Summary
I asked Finnick once how he knew he loved Annie, and he said she snuck up on him. I think after all this time it has been the same for me." This story is a version of how Peeta and Katniss grow to love one another in the end, but it stays true to Katniss's character in a way that reviewers elsewhere have said is unique. I promise a few surprises along the way.

Summary
“You never cease to surprise me Giyuu,” she mused, trailing her fingers down his arm and into his open palm. “Sometimes I think I have you figured out, but then I turn a page and there is more. Was everything always there underneath this inscrutable face of yours?” she asked, placing her hand on his cheek.
He turned to kiss her palm, exhaling warm breath, taking a moment to think about it.
“No,” he said, the word caught in her hand, before he turned to her with a searching look. “And yes. I built up walls trying to control my grief and my guilt. After a while, I just couldn’t access pieces of myself.”
“Hmm,” she murmured, smoothing his hair away from his face. “What brought down your walls?”
He leaned slightly into her touch but looked away over her shoulder before he answered.
“Tanjirou. And Nezuko. When I found them in the forest on the day she was turned into a demon. They were the beginning.”Series

Summary
He holds out his hand. She looks down at it. It always comes to them reaching for one another in one way or another. Reaching to grab and gain control. Reaching to strike with a laser sword. Reaching to test a boundary or lack thereof. She takes his hand, but then pulls him to her in an embrace. They release their hands and wrap their arms around one another, her cheek to his chest, his mouth to the top of her head.
It is strange to hold Ben. The physical sense memories of their various battles are still very real in Rey’s mind. She remembers the focus and ferocity with which she attacked him and the brutality that answered her every blow. The hands and arms that hold her so gently at this moment have barraged her with killing blows a hundred times. Blows that she returned with equally vicious intent. But since the moment she sensed his presence on Exegol, she’s felt nothing but affinity for him. That he is on her side is an unassailable truth. -

Summary
He moves toward her, hands held out. She stops suddenly and looks at his hands, at the simple humanity in the gesture of him reaching toward her with bare and open palms. She remembers the other times he asked her to take his hand, and again she feels that strange ambivalence, a push and pull. In the end, it is curiosity that pushes her to want to reach back. Spoilers.
