Paradox

Lin Sinan never would have imagined, not even in her wildest dreams, that by a twist of fate, she would end up in a physical relationship with her own younger brother.

The little puppy from back then had inexplicably turned into a big bad wolf.

He wanted not only her body but also her heart.

A paradox, a forbidden love.

A scheming, cunning younger brother x A tsundere older sister completely dominated by her brother.
