I'm a Bad Guy

(1V5+ time travel (game) + rescue + shameless + yandere (micro) + system, modern) "Are humans made up of body or soul?" "Nourish everything in the name of love." —— According to legend, a man suddenly felt a certain power while studying in the middle of the night. Successfully traveled to the world he was playing in. Just... There seems to be something wrong with this world. I just wanted to be in love. But... Sin does not lead to death. . . The warm and welcoming girl next door. The delicate and squeamish fiancée of a rich family. A mature female senior who likes to be fucked hard by bullies. A female academic who doesn't know how to love. And, his sister, the master who sends her off. ——— Thank you for teaching me how to love myself and others when I least knew how to love. I really really like you. I love you so much, I really want you to be one with me. Tell me. Can you only love me? Sister, don't always say it's for me, okay? Don't always think about me. . . Your sister, I am not that fragile, go ahead and pursue the person you like. What about you? Hey, I'll steal it from you. . .
