When Cloud first returns, Aerith takes him to her home and makes a bed with pink, fluffy sheets on the couch. He's surprised at first, a look of indignation on his face, followed by a grimace as Aerith smiles and leaves the room.
Cloud is tempted to follow her- perhaps ask for a good night kiss?- and ask for some different sheets, but controls himself and settles down on the frumpy magenta couch with the pink sheets.
The next day, Aerith greets him with tousled brown hair and a "Hmph" and he cracks a smile. It takes her a while to process that Cloud is shirtless and has a black wing protruding from his shoulder/back, ('whatever, it's still early in the morning', her mind grumbles) and drops her coffee cup.
The blond winces and the wing folds back, out of view. "I'm sorry," His voice is cracked, just like the cup now laying on the floor, and full of shame and regret. "I was going to tell you about it later, when we were all settled."
Aerith says nothing, just smooths back her hair.
The room is filled with deafening silence until Aerith clears her throat and walks towards him with timid, barefoot feet, carefully avoiding the glass. And then she lays her hand on his shoulder and smiles-only Aerith can smile like that-, closes her eyes, and laughs.
"Do you want some coffee?" Cloud looks up, surprised once more, and mimics her own actions.
"Yeah, I would."
"Wow."
The word is quick and filled with awe as Aerith first gets her glimpse of Tron's virtual world-his world. Sora is grinning, like always and Cloud is pulling at his skintight jumpsuit.
Everything is doused in blue here and the outfits are so futuristics. She admires her own outfit, with the pink lines running up her clothed arms and legs, the positive sign planted firmly on her bust.
She turns, her face pink with excitement and bursts out laughing at Cloud's expression. The way his blush turns even more vivid when he sees her watching him picking at his clothes is priceless and Aerith cannot help herself as she zooms towards him and pecks him on the cheek.
Cloud's room is strange. There's nothing but black and white in his room, except when she's there.
Her face florid from messy lovemaking, lain out on the black sheets, her nude body heaving with sleep. The tanned skin clashes with the room's general theme, but her brown hair matches quite well.
The spiked head of blond hair that's resting on her lower stomach watches her sleep and decides that he could use a bit of colour in his room, and if Aerith stays here forever, this will be all he needs.
