I Don't Want to Be Violently Doted on by My Brother, the Gangster Boss.

[Pseudo brother and sister + forced love + double cleanliness] [Cruel and yandere gangster x delicate white cut black growing up weak girl] Ke Ze and Ruan Yihan grew up together in an orphanage. They have a deep love and have been brother and sister for seven years. Reunited after a long absence, Ke Ze has become the ruthless second son of the Ke family, the underworld in S City, and is running the underworld. When he sees his sister again, Ruan Yihan is tied tightly to his bed with ropes. With tears in her eyes, she called him: "Brother," and Ke Ze's heart, which had been hard for a long time, suddenly softened. "Brother will never let you go again." Ke Ze carefully untied the thick rope. Ke Ze seems to still be the gentle brother in Ruan Yihan's memory, but there seems to be subtle changes. Until she escaped and he caught her back in person, the brother tore off the mask of gentleness and revealed his true face of a cruel and yandere. "Sister, how can you abandon your brother?" "If you don't behave, my brother will punish you." - She didn't expect that Ke Ze would put customized soft shackles on her just to tie her tightly to his side. She became the canary raised by Ke Ze. Their once warm home had become a prison that locked her tightly. - Ke Ze didn't know when the love between brother and sister had subtly turned into love between man and woman, and love between fish and water. In the past, he traveled in the underworld, and he wanted power, status, and wealth. Later, all he wanted was to spend time with Ruan Yihan day and night. He kissed her, fucked her, gave her everything she wanted, but refused to give her freedom. - She couldn't fly away from him. But she is a free bird, and she doesn't want to be imprisoned by anyone. Even if that person is the brother she has liked since childhood.
