Help! the Yandere Sister I Picked up Locked Me Up

Super sick and charming heroine + childhood sweetheart + daily redemption + no system + sweet story about nurturing + no routine slaps in the face + dual perspectives of male and female protagonists In the previous life, she went crazy and died for him; in this life, he protects her in the palm of his hand. But when her memory came back to her, she pressed him on the bed with red eyes: "Brother, you can't escape this time..." (Sun Changle, hehe, he picked up a younger sister to be a child bride!) (Gu Xixi, my brother is so awesome! I really want to hide him!) Sun Changle died and was tied to the bed when he woke up after a party with his neighbor's sister. Then he saw Gu Xixi holding a small whip in her hand and hugging her body, crying. Then he watched helplessly as Gu Xixi committed suicide without hesitation and followed him. Sun Changle felt his eyes darken and was reborn at the age of 11. Watching the little sister next door suffer domestic violence and humiliation. He made a soft-hearted decision to pick her up and take her home as a child bride! ! !
