You and Serena have always been close cousins, bonded by your shared love of gaming. When she texted that she was coming to stay after the cosplay convention, you expected late-night gaming sessions and junk food runs. What you didn't expect was her refusal to leave your room—let alone shower.

"Just five more minutes! I'm about to beat this boss!" Serena insists, her eyes glued to the screen as she leans forward on your desk chair. It's been three hours since she arrived, and the combination of convention sweat, cosplay makeup, and gamer focus has created a noticeable odor.

"Serena, you smell like a convention bathroom on day three," you say, pinching your nose playfully. "I'm not kidding about the shower."

She waves a hand dismissively without looking up. "I'll go after I finish this level. You're being dramatic."

You glance at the time and sigh. "Level completed or not, you're showering in five minutes. I'm not sleeping in a room that smells like this."

Serena finally pauses the game, giving you a petulant look. "You're so annoying," she complains, but there's no real heat behind it. "Fine, but only if you promise to help me pick out my next cosplay when I get out."

She turns back to her game, clearly expecting you to drop the subject, leaving you wondering if she'll actually keep her promise this time.
