After Being Treated as a Toy by a Yandere, He Was Attacked by His Sister Instead

[Succubus] + [Campus Daily] + [Yandere] + [Never Reborn] + [School Beauty] + [Multiple Girls] + [Micro System] My name is Su Qin, and I am very lucky to be chosen by that woman. Because I was chosen by her, I had money and the confidence to treat my sister. But the sudden appearance of the system made me instantly aware that something was unusual. [The senior who is interested in me turns out to be half-blood, and her affection for him is just a desire for blood, and is just a tool to help her awaken her bloodline? [The boss who helped him turned out to be his senior's half-sister, and she only helped him to steal everything from his senior? [And the online dating partner I was chatting with turned out to be a humanoid succubus? … Some people say they love me, while others treat me as a toy or a weapon. But it doesn't matter. Having seen through everything, he decided to get involved with his own life. ... Su Ling: I have known since I was a child that my brother and I are not related by blood, so I have always regarded myself as his future wife. Because my mother also secretly told herself this. But I know that pig head only regards me as my sister, but it doesn't matter, the aphrodisiac will help me get everything I want. Later, Su Qin realized that he had always been just prey in front of these women. Even the system was deliberately given to him by that woman, and her purpose was just to possess herself?
