I'll Teach You, Marianne. - Chapter 162 - The New Anne

Born into one of the wealthiest families in the country, Layla Rosenzweig's true identity is taken away at the time of her birth by the mistress of her father. She is forced to live as the illegitimate daughter of the Rosenzweig Family. Everyone treats her no less than an outsider in her own house. “This is mine. That is mine. In fact, everything is mine,” Layla's half-sister told her. Everything that belonged to Layla is given to her half-sister, including her boyfriend. Then, she is forced to marry her ex-boyfriend's ruthless uncle, Lucius De Salvo, the most terrifying man in the country. Lucius De Salvo is known for his ruthless ways to get his work done. His name is enough to terrify people. It is said that he is a man devoid of emotions. He will find pleasure in people's pain and misery. He loves to torment those who come under his radar. But why is he so lovely to Layla? Or is it just a pretense?“Are you ready for the wedding night, Darling?” Lucius asked. “I've desired you for a long time.” “What?” Layla was shocked. “Why would you?” “Because you are Layla Rosenzweig. The woman I like.” With that, he captured her mouth for a passionate kiss.

His name is Gao Yang (高阳), not a lamb (羔羊: gāo yáng), okay! If a gentle sheep gets upset, it will bite. Believe it or not!

Gao Yang a sheep in wolf’s clothes: Don’t come again! Otherwise, I will be rude!
Qin Shaoyan: Oh? Why not?
Gao Yang: I… I… won’t cook for you!
Qin Shaoyan: It doesn’t matter, just eat you.
Gao Xun: What if Dad dies after being eaten by Father? Waiting online, urgent!
