They said evolution takes millions of years. They were wrong.

Alex Chen is a broke, burned-out programmer stuck in a dead-end tech job—until he stumbles upon a mysterious digital interface only he can see: [SYSTEM DETECTED]
With one blink, his world changes. Strength. Reflexes. Memory. Intelligence. Everything is upgradable.

But he's not the only one. Others are evolving—faster, stronger, more dangerous. Shadowy corporations want to control the system. A hidden cabal is already rewriting humanity. And at the center of it all is a name whispered in the darkest parts of the net: Viktor.

As Alex unlocks new powers and uncovers buried secrets, he must decide:
Will he become a weapon, a savior… or something far beyond human?

The game has started. The rules are broken. And humanity is just the beginning.

“No woman has ever made this cold heart race,” he murmurs.
“Except you.”
......

Valentine’s Day was supposed to be the night I told my best friend Ethan how I felt.
Instead, I kissed his dangerous twin.

A month later my mother married their father. Elias became my stepbrother.
He still has private photos of me I never knew existed. When I find them, trust nearly shatters. He destroys them—but forgiveness is harder.

While I fall for the wrong brother, Ethan’s jealousy turns darker. He uses what he knows about Elias’s past, and about Vivian, the older woman who once left real scars, to make me doubt everything.

Vivian contacts me herself. She doesn’t want him back. She only warns me about the difference between being wanted and being possessed.

My mother demands I end it for the family. Ethan threatens to expose us.
Everyone has decided what I should do.

I spent three years waiting for Ethan to choose me.
I will not let anyone else choose for me now.

Even if the brother I choose is the wrong one.
