(I feel this drabble merits a bit of warning -- it's a tad creepy in my opinion, and I was accidentally channelling a psycho character I role-play when I wrote it. All grammatical errors are intentional, so please don't call me on them.)

Seto wants to kick him out, and he can't figure out the best way to do so.
He could wake Bakura, tell him to leave and not come back, and hope for it to turn out well.
No, that wouldn't work.
Bakura would smirk, agree in that peculiar way that meant Seto'd done something he considered cute, and leave. The following evening, he'd turn up and the cycle they'd developed would start all over again.
Seto thinks he needs a better method. He's tried the last one before (or at least, anything and everything similar), if his prediction is worth anything. It seems to be very accurate and plausible, in his opinion.
Maybe he can do something more severe.
Maybe he can pack up and move to a remote location without telling Bakura. Take Mokuba, his work, send e-mails on how to keep his company run.
... But that wouldn't work either.
Bakura was too stubborn. He'd find a way to follow, be it via threats or information theft or pure dumb luck. Bakura was like a vampiric bloodhound, and Seto was his blood-letting target. Or prey. Or whatever you called the thing a bloodhound was supposed to find if it were bleeding.
Seto wants to be rid of him. He knows one way to do that, but it's very permanent and very illegal. And very, very bad.
But Seto doesn't care. He's frustrated and annoyed and tired. He doesn't want this forced affair anymore. He doesn't want these bruises and sore muscles and lies and hurts and everythings.
He could strangle Bakura. But that takes a long time and Seto thinks that maybe if Bakura opened his eyes, Seto would be the one who lost the fight. Bakura had a strong will to survive.
He could poison Bakura. But knowing the theif, he'd noticed.
He could stab Bakura. Yes, that was promising. Pretend he wanted Bakura's hands and tongue and everything, and then cut the thief when he wasn't paying attention. Bakura would like that. Seto could push and push until it was far enough along that Bakura would die.
There, he's said it.
He wants Bakura dead.
He looks over at the white ghost collapsed on his bed, naked and unashamed of his nakedness, asleep and unafraid in his rest.
He wants to kill Bakura.
And he knows he can't.
