[Possessive, sensitive sweetheart × seemingly gentle older brother]
[Six-year age gap + secret love + obsessive romance + guiding older brother + groveling redemption + awakening + a touch of System]
Gu Xue was a child no one wanted.
Her loving birth parents passed away, the older brother she depended on left, and even the adoptive parents who had taken her in by chance were gone.
Only after falling seriously ill did she awaken and learn that she was, in fact, a dispensable supporting character in a book.
Yet this insignificant little character survived to the end of a story where everyone but the male and female leads either died or went mad.
**
An Fengchun had never known his younger sister could be so crazy.
She used to be quiet and well-behaved, never causing him the slightest trouble.
After his parents passed away, Gu Xue changed.
She became unreasonable and difficult, contradicting him at every turn.
During that time, Gu Xue could easily cross his boundaries, provoke his anger, and… stir his desire.
Perhaps losing her parents had affected her, so it was only natural for her to become a little rebellious.
It was all right. He would teach her properly.
[The heroine was adopted by the hero’s family, but her household registration remains with her birth parents. There are no legal complications, and the two are not related by blood.]
