MTL - My Koi Sister is Three and a Half Years Old - Chapter 307 you are a real dog

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.

When choosing the companion system, Congliang did a trick, palace fights, house fights, scumbags, counterattacks, and other systems that seemed to be particularly wasteful of brain cells, and pulled a particularly pure-looking “Scum Girl Congliang System”.

Being good means being a good person, and being a good person is simple.
However, after starting the time-travel mission, Cong Liang discovered that her trapping system has another more appropriate name – “Sura Heart Hunting Field”

- Description from novelbuddy

After seeking pleasure in the nightclub and a night of romance, he discovered there’s a seed in his stomach;

streak of being publicly humiliated in every story route. In other words, he was the designated cuck of the game Academy of Roses.Too bad for everyone, Cassius is now possessed by Arawn—a burned-out gamer who just tried to kill himself after exacting savage revenge on his sister’s cheating husband.Waking up in the body of the most pitiful character in eroge history? Not ideal. Finding out his missing sister has also been isekai’d and is now pretending to be Cassius’s noble “sister” to avoid suspicion? Wild. Realizing she’s about to be married off in another forced engagement plot? Yeah, fuck no.Armed with system powers(everyone has it), broken stats(for your average joe), and a big 'sister complex'(Not Incest) on steroids, Arawn has one simple plan: Live a peaceful life with his sister, for it he would, Break the rules. Shatter the narrative. And if anyone tries to play the protagonist? Use them for his own plans.This time, the cuck’s got teeth. And he bites back—in the most painful ways.—————Warning: The MC is a villainous character, he is psychotic, manipulating, borderline insane and unhinged. So, please keep that in mind
