Disclaimer: This being fan-fiction, I do not own X/1999 by CLAMP.
Warnings: not sure. Sex, other.
This is purely self-indulgent and it's unlikely I will continue this. I don't have any more plot planned, and I just don't have the stamina to write long/multi-chapter fic. Enjoy?

Prologue
Two things happened that led up to Subaru's proposition.
The first was, bizarrely, something Kanoe had said. Despite her minimal magical talent, or perhaps because of it, she had developed an incredible ability to manipulate anyone into doing anything she wanted. This, combined with her unparalleled ability at acquiring gossip and those catty conversations with the Dragons of Earth's Kamui, somehow resulted in Subaru finding out about their remarks that "if Sumeragi wants Sakurazukamori's attention so bad, he should try spreading his legs".
The second thing was Subaru taking this suggestion seriously.
It had been– oh, Seishirou had been surprised to see Subaru at his door, and it was lucky that he found Subaru's clumsy attempts at seduction enduring, but Seishirou had been eating ribs and his hands had still been sticky and he thought, Subaru-kun never eats enough, so he ended up sticking his fingers and his tongue in Subaru's mouth. After that, after they had fucked on the kitchen diner floor and Subaru had gone for a shower, and while Seishirou tried to clean the stains off the tiles, Subaru had come out in his still soiled clothes looking as determined and lost as ever.
"You can't go out in those clothes," Seishirou said. "I'll wash them with mine, and they'll be dry in the morning. Bathe with me."
Perhaps Subaru had been thinking more clearly or maybe he hadn't been thinking at all, but somehow during their bath he had asked Seishirou if he was lonely. "I was lonely," Subaru said. "You were the first to treat me not as a freak, or the Head of the Sumeragi Clan, but as a person," and neither men lost the irony in that.
When Subaru offered to wash his back, Seishirou agreed. "You could kill me like this," as Subaru soaped his shoulders from behind. "Wrap your arm around my neck in a chokehold; hold it until I stopped breathing." Subaru leant his head on Seishirou's right shoulder and smiled to himself, because the idea in his head was his own. He lifted his head up and leaned into Seishirou's ear.
"Let's make a bet," he murmured, and Seishirou listened carefully. "I know that man I fell in love with never existed, but I could never fall out of love with him because I never knew the real you.
"Let me stay with you until the end of this year, and let me know you. Be honest in everything you say and do with me, hurt or love me if you wish. Tell me about your childhood, your university days, what you do in your spare time, and I will try everything in my power to accommodate and understand you.
"When this year ends at the final battle, I will tell you if I am still in love with you, and if I am not then I will kill you as I should. But if I still love you, then kill me, and so take me out of this decade of hell." Subaru lifted his hands from both shoulders, wrapped his arms around Seishirou's chest and kissed his ear gently.
"But until then, I will let you go."
