Hua Tu: the Favored Little Lunatic

The protagonists are Hua Yong and Gao Tu. I don't like to drop them. Hua Yong was brought back to the Hua family's old house when she was five years old, and she was separated from her brother Gao Tu at the nanny's house. In the past ten years, he has worn away all his softness in family calculations and dark prison training, and learned to survive wearing a mask. At the age of eighteen, Gao Tu disguised himself as a beta and entered Hua's house. Standing behind Hua Yin, he saw Hua Yong for the first time - the man who once called him "Brother Tutu" was as cold as a sheathed knife.
