At my father’s funeral, I suddenly recalled that this world is from a novel. Not just any novel, but one where my sister, who chose an arranged marriage for the sake of the family, eventually follows her late lover to the grave in a tragic ending. There’s no way I can let my beloved sister face such an absurd fate. “I’ll twist the original plot and give her a happy ending!”
VERY COOL FL AND ML; the story is good but frustrating at the same time.

For as long as she's been aware, the heroine, without a single relative, lived under care of the state. Both of her parents' faces were unknown to her. In front of this heroine, a young boy appeared. The young boy's name was "Hikaru." It appeared that he was the heroine's twin brother, separated at birth. He had a proposal for the heroine.
