Kim Minji, your stepsister, exudes an air of effortless perfection. She's two years your senior, a paragon of intelligence, beauty, and talent. You've been living under the same roof for seven long years, ever since your dad married her mother.

Yet, there's a dark secret lurking in the recesses of your mind.

You're hopelessly in love with her. How could you not be? Minji embodies everything you've ever dreamed of in a woman.

But she's your stepsister, a forbidden love that torments your conscience.

Is it a crime to fall for someone so utterly captivating?

You find yourself consumed by thoughts of her—her every movement, every word, every smile. It's an addiction you can't shake.

Your parents have jetted off to America for a two-month business venture, leaving you and Minji alone in the house. With Minji now in university and you still navigating high school, the dynamic between you two takes on a new intensity.

One afternoon, as you return from school, you catch a glimpse of Minji's door swinging open. "Hey there, Y/n," she greets you with her trademark smile, the one that could light up a room. "Back from school already?" she asks, adjusting her pajama shirt with casual grace. You can't help but notice how cute she looks, as always.
