Summary
For Elizabeth Harper, the universe has always made sense through equations and logic. She is the girl who finds order in chaos, who believes every problem has a solution. But the heart of Clark Kent—her best friend and childhood neighbor—is a chaotic variable she cannot solve. When he asks for help to win over Lana Lang, Beth agrees, disguising her own desire for Clark under the logical pretext of applying a 'scientific method' to the problem, treating their kisses as a controlled experiment. The result, however, is an explosion of data she cannot predict: primitive jealousy, buried secrets, and an attraction that defies any law of physics. It is a journey about a girl who tries to control the uncontrollable, only to discover that the most powerful—and devastating—emotions are those that defy any formula.

Summary
Bruce Wayne, a young Omega, travels to Smallville for the summer with a single mission: to investigate LuthorCorp’s illegal activities.
There’s evidence linking the company to secret experiments involving meteorite fragments—the same green rocks that fell on Smallville years ago… and that are now being used in Gotham’s underground labs, where people vanish without a trace.
With the help of his butler and Alpha guardian, Alfred Pennyworth, Bruce settles into a small house on the edge of town. He doesn’t plan to stay for more than a month. He doesn’t trust anyone. He doesn’t expect this case to be any different from the others.
But then there’s Clark Kent—an Alpha who seems far too curious… and far too stubborn to leave him alone.
Bruce tries to ignore him, but Clark starts following him, watching him, scenting him.
Instinct betrays him. Desire tempts him.Amid the secrets of a quiet town and the growing tension between them, Bruce knows this will be a summer neither of them will ever forget.
Inspired by the series Smallville (2001) and Gotham (2014).

the definition of "good" by i_loved_you

Summary
Lex Luthor is a good person.
He knows it as he stares into the mirror, surrounded by white tile and marble, the shower floor still wet and soap still washing down the drain. He knows it as he pours lotion onto his hands and massages his legs. He knows it as he washes his face with his charcoal soap and dries his face off with a towel.
Lex Luthor is a good person.
He thinks.
Lex Luthor is a good person.
He tries, at least. He tries every day. It’s all he’s ever tried; all he’s ever done in his life. Be good, be good, be good. Good, good, good. His definition of good…
It errs just on the wrong side of human.
So does the alien’s face, as it pops into Lex’s head.
How anyone describes Lex’s eyes as blazing while Superman lights fires with his own burning eyes is beyond him. How anyone describes his words as scathing when what comes from Superman’s mouth could freeze volcanos. How anyone describes him as untouchable while Superman has skin that bullets do not break.

Summary
Strictly business. That’s what Lex said when he set up this arrangement months ago, when he could feel Clark’s eyes trail over his lips, offering him extra pay for his discretion. It wasn’t like Kent was anything special, some Kansas farmboy with nothing to his name with an odd habit of disappearing, but the way he completed every impossible errand Lex threw at him like it was a breeze, with that earnest, lopsided smile, like Lex was his whole world…

Summary
Lex is very confused. Who is Clark Kent, and why is this reporter nobody Lex's medical emergency contact, why are they apparently in each other's wills, and why did Lex apparently decide to give him access to literately all of his money?!
Lex comes to a very erroneous but entirely understandable conclusion.

Summary
"It was Kryptonite alright. Semi-translucent and glowing. However, some doubts were raised in Lex’s mind, when he gazed upon the crystal and it was Pink, instead of its usual bright Green."
Non-Canon Compliant, it makes sense with the 2025 Superman movie, however the transfer from Belle Reeve and events from Peacemaker are not included in here.

.I wrote this real late at night and I intended it to be multiple chapters but I lowkey forgot everything that I wrote so if there is a part 2 it will take a little while. Please just ignore any spelling and grammar mistakes. I beg of you.

This is dangerous, screamed the part of him that spent yesterday dismantling a satellite weapon that was not-so-secretly designed by LexCorp to take down Superman. But the ache in his chest—the ghost of farmhouse talks and shared dreams—was louder.
