Chapter Text
Kara Zor-El Danvers, or Supergirl, as National City called her, considered herself a mindful person. Mindful of herself, her powers, her choice of words, and mindful of her actions. Mindful of others too. How they behave, what they say, but most importantly, mindful of their quirks, tips, tricks, and most of all their secrets. When you can tell if someone is lying based off their heartbeat, you learn a thing or two about people.
"Its the details, the little things," Kara would often say to herself and her older sister Alex. Kara hardly considered herself 'oblivious', much to Alex's dismay.
"Alex, how exactly can I be 'oblivious'? I can tell if someone is lying or hiding something by listening to changes in their heartbeats, breathing patterns and the tone if their voice!" Kara often retorted. Kara only ever got one response.
"That's not all you need to pay attention to dufus," Alex often sighed.
Needless to say, the Super thought of herself as a lean, not too mean, lie detecting, justice seeking machine. Aliens? No problem. Humans? Literal piece of cake (and cake never stood a chance against Kara). Everything from petty squabbles to near world ending disasters, Kara had it handled, with help of course.
However, just because the Super was a 'Jack-of-all traits', Supergirl-wise, she certainly wasn't the master of one very specific thing. Well, person really.
Lena Kieran Luthor.
Literal enigma, as far as Kara was concerned.
Multibillionaire. CEO. Genius across the board. The most beautiful, well, entity Kara had ever seen. Lena cared for others, and the planet. Giving back as much as she was capable. Turning her families, and eventually her brothers xenophobic horror filled company, into one filled with promises of cancer cures cleaner air and oceans, but most of all, hope. The woman was brilliant, confident, headstrong and only 25.
"How does that even work?!" Kara often thought.
Meanwhile "here I am" Kara thought jealously. Junior of all the Junior reporters. Tripping while standing still, food obsessed (kryptonian hunger is both a blessing and a curse) and struggling to pay rent at 27.
And somehow... the literal genius that is Lena Mother Fucking Luthor, was "bestfriends" with none other than, Kara Danvers.
At least that was what Kara thought, until lunch that day. Until...
"The Incident".
