What The Day My Stepbrother Knows My Dirty Secret is about
She finally hands over a love letter, only to give it to the wrong boy, her crush's rival. Then comes the worse discovery. The pages are not a love letter at all but an explicit story she wrote herself.
The humiliation should end there, but it does not. The boy who now knows her most embarrassing secret turns out to be her new stepbrother, and he is every bit the devil she took him for. Living under one roof, he keeps her secret dangling over her head, and their constant sparring slowly turns into feelings neither of them expected.
