The next morning, Yusuke got a shock when he looked in the mirror. Over the exact spot were Touya had marked him was… a marking. A small black design, a heart with a teardrop hanging from it. Yusuke put a hand to it curiously, rubbing to see if it would come off. It didn't. Touya entered and saw it too.
"I guess that's our mark." Touya said. He showed Yusuke; he now bore the same design in the same place. "It's different for every couple. It depends on their attributes and personalities and what not. It's always black, unless one of us is in trouble. Then it glows red and burns." Touya explained.
Yusuke nodded. "Somehow, I knew that. I don't know how though. And I couldn't have said it if you'd asked. I just… knew." Yusuke wrapped his arms around Touya.
"I'm not surprised," Touya answered, "If you knew to mark me… the rest would have come with that knowledge, I suppose." He looked up at the heart and tear at Yusuke's neck, fascinated that he could share something so symbolic with his love. He kissed the tiny black heart and tear, in thanks for their presence, which was so sacred to him.
Yusuke smiled, "Wherever the idea came from, I'm glad it came to me. I like you marked. Now everyone will know. No one else can have you but me. You are my most treasured of all. Nothing else matters as you do. My beautiful Toy-chan."
Touya closed his eyes and smiled contentedly, burying his face against Yusuke's chest. He knew some people would be offended or upset by how possessive Yusuke was, but he rather liked the idea of belonging to Yusuke through all things. He was Yusuke's most treasured possession; he knew it and loved it. "Yours. I love being yours, Yusuke. I'll always be yours; I am of no concern to myself, for you always take care of me. And in return, I will care for you and do as you please. I love you, all my heart, all my soul, all my mind, all my body, all my tears."
"You won't have to shed them anymore. If I can save you from shedding another tear, I'll do it. I hate it when you're sad, Toy-chan." Yusuke said, wiping at Touya's face, brushing away tears that weren't there, but were once, and will be.
"No… Sometimes I need to cry, even when I'm not sad. I cry when I think how lucky I am to have met you, when I think of all you've done and do, and I cry when we make love. I never want those tears to stop. I want those tears forever. Those are my crystal tears. The others are only salt tears. Those are the ones you want to stop."
Yusuke nodded. "You're right, as usual. We both have our crystal tears and our salt tears. We'll make a world of crystal tears. Invitation only." Yusuke grinned at this last, to block unwanted visitors. Touya smiled back, contented.
