Heroine: the Young Boy Who Was Brought Home

"Sister, I'm so scared..." As soon as I traveled to this female world, I turned into... A doll cat? ! It was even bought home as a birthday present by a beautiful sister named Su Yi! Just when I was desperate, a mechanical sound suddenly sounded in my mind! Bite! The host's strong desire for survival is detected, and the luck collection system is successfully bound! [Task release: Bind the son of luck, collect his luck, and obtain energy] What? As long as you interact with your sister, you can get rewards? Bite! The host interacts face-to-face with his sister and unlocks the achievement "Close Contact", with +1 physical fitness and mastery of the coquettish skill! [Ding! The host successfully made his sister's heart beat out of control and was rewarded with mastery of tea art] Looking at the beautiful sister in front of me who is cute and sassy, but completely defenseless against me. I laughed. Sister, do you think you are raising a harmless kitten? No, you are raising the future master of the world! From today on, I have the final say in this home! Uh... Sister, I'm hungry. Can I feed you first?
