A story about an adopted little boy who grows into a big, bad wolf...
1. Gu Jingzhou (top) × Gu Yu (bottom)
2. One child is the bottom, and the other is his younger sister. Neither is related by blood to the top.
3. Older top raises younger bottom. The top has an ex. Maybe a gentle top paired with an obsessive bottom.
4. Illogical story with clumsy writing. I'll add content warnings later, and the blurb may be revised.
Theme: Sincerity can move even stone and metal.
