A/N: What Takato doesn't overhear.
Ryo doesn't even look at her. "Go away, Ruki."
Ruki is unimpressed with what she is hearing. "This is my house; this is, as much as I hate to say it, my birthday party. You can't tell me to go away."
This is the most dull-sounding she's ever heard Ryo. It worries her. She'd expected more of a response. "In that case, leave me alone. You've caused enough trouble already."
"You're a bastard," she replies reflexively, but without any real heat. Honestly, it doesn't sound like he needs it.
"And you're not helping." Ryo glares. "Go sing your stupid song."
