My mafia step sisters

Kang Y/N is an ordinary fifteen-year-old girl... or at least that's what everyone believes.

Quiet, introverted, and often overwhelmed by even the smallest problems, Y/N spends most of her time avoiding attention. She struggles with stress, gets attached to people far too easily, and has never fully recovered from losing her father in a tragic car accident years ago.

Living alone with her mother, Kang Sojin, Y/N believes she knows everything about her small family.

She couldn't be more wrong.

Hidden behind computer and anonymous usernames, Y/N secretly lives a double life as a talented hacker capable of uncovering secrets that were never meant to be found.
Meanwhile, her mother has been hiding a secret of her own.

A secret that is about to turn Y/N's entire world upside down.

On the other side of the city stands one of the most feared families in the underground world-a family ruled by five powerful sisters known for their cold hearts, unmatched influence, and dangerous reputation.

Their names are feared.

Their power is respected.

And their family is about to collide with Y/N's in a way none of them could have imagined.

As hidden truths come to light, secrets unravel, and new relationships are forced together, Y/N finds herself caught between two completely different worlds: the quiet life she's always known and a dangerous world filled with power, family drama, loyalty, and enemies lurking in the shadows.

The biggest question isn't whether Y/N can survive this new life.

It's whether the people around her can handle the secrets she has been hiding all along.
