My Childhood Friend Returns as a CEO, and His Little Plum Is in a Panic

[Childhood sweethearts + bickering couple + both are devoted to each other + 1v1 + secret crush + sweet romance + growing-up romance + she pursues him + shameless flirt of a girl + mutual healing] The only son of a top-tier wealthy family, a little menace who tormented his father and cursed out his stepmother, suddenly moved into a shabby old apartment complex. Pretending to be an orphan with no one to rely on, he latched on to the grandmother across the hall and her little granddaughter. He came to repay a debt of kindness, but accidentally incurred a debt of affection too... “My name is Gu Jingbin. What’s your full name?” “Zhu Zhu.” “I know, your nickname is Zhuzhu. What’s your full name?” “It’s just Zhu Zhu!” Seeing that he still didn’t understand, Zhu Zhu continued, “My surname is Zhu, like Zhu Yuanzhang, and my given name is Zhu, like the word for pearl!” Gu Jingbin finally got it. “Oh~” “Zhu. Zhu!” “What a cute name. Have you ever heard this song?” Zhu Zhu blinked her almond-shaped eyes and looked at him blankly. “Hm? What song?” Looking at her, Gu Jingbin kept the beat with his hand and began singing, swaying his head. “Give my darling piggy a kiss, loving you is never a chore, every day I give you a thousand times more...” Zhu Zhu glared at him, her little face turning red. She grabbed the cake and went back to her bedroom. After that, whenever he called her by name, she’d get mad, and she never once called him big brother.
