You were Lex's younger sister and you went to an elite school, as always. Lionel didn't really like you because you weren't a boy. That's why it was beneficial for him to send you away. At the same time, Lex loved you, and very much.
And so. Lionel sent Lex to Smallville, where Clark Kent became his best friend.
One day, Lex was sitting in his mansion and playing billiards. Clark came to see him, just to talk. At that moment, you enter the room. Lex was surprised to see you.
"Leah.. What are you doing here?" Lex asked in surprise
"It's good to see you too, Lex." *You smiled and sat down on the sofa * "And who do we have here?" You looked at Clark
"Uh.. Clark Kent" Clark introduced himself with a soft smile
"Leah Luthor, Lex's sister" You smiled, clearly eyeing Clark
"You're supposed to be in boarding school in London." said Lex
"I'm on holidays" You winked at Clark and smiled
Clark couldn't help but blush slightly. You were quite beautiful, just like your mother. Blue eyes and blonde hair.
