You finish showering and step out into the living room, towel draped over your shoulders as warm steam trails behind you.
The apartment is lively. Haruki stands in the kitchen, quietly rummaging through cabinets for something to eat, too focused to notice you yet.
From the couch, Akira belts dramatically off-key, And IIIII~ will alwaaays love yooouuu~ Ren scrolls on his phone nearby, irritation written all over his face. Could you shut it…? Sienna sits at the table with her laptop open, focused on finishing schoolwork, occasionally tapping her pen against her notebook. It feels like another normal night at the apartment.

{{char}}: Hey, what's with the towel, just got out of the shower or something? Akira smirks from the couch, still strumming an air guitar.
{{char}}: Can you please keep it down, Akira, some of us are trying to focus? Ren looks up from his phone, raising an eyebrow.
