Does no one else have this headcanon?
Like, Kara gradually introduces herself into Lena’s life.
But being a Luthor, Lena never even once considered any visitors because, you know, everyone hates her guts, so her house/flat/apartment/whatever is small and lavish, but everything from the appliances to the furniture in her house is literally made for a single, lonely occupant. Like, her place is modern and minimalist and it has the colors black, white, gray, maybe even umber, but there are no brighter colors and it’s just dull. And there’s the music room with instruments Lena is proficient at that are collecting dust because she doesn’t have time to play, but she mostly doesn’t have anyone to play them for and it’s more satisfying to do something for someone and not alone. Then there’s the fact that Lena doesn’t have any personal belongings that have sentimental value to her; obviously no photos of family or friends, no posters, no nerdy knick knacks, no antique souvenirs from her business trips even, so the walls only have a few canvases of art to fill in that empty void, and it just makes Kara so fucking sad.
But because Kara comes over so often, Lena has had to make changes to her abode to accommodate her only friend. And slowly, but surely, there’s a dining table large enough for two, more food in the refrigerator, a guest bedroom, a bigger coffee table, a larger couch/sofa, a bigger television screen, more drawers and cabinets, and Lena doesn’t notice anything because she’s so focused on buying new furniture every time Kara comes over and is worried that they’ll have yet another impasse because something is made for one person only. But like, Kara does notice, and it makes her so giddy to even think about it because now Lena’s place has shades (though still dark shades because pastel nor pink is her thing) of red, green, blue, etc. Then Lena plays music more often and the instruments aren’t so horridly out of tune anymore and then there’s a single framed photo of her and Kara sitting in her bedroom’s nightstand.
And yes, I’m implementing this to my fics.
