My Older Sister is the Villainous Young Lady

"You're a villain." Wein pointed at a girl who was elegantly eating cookies. The girl nodded in agreement, happily humming and nodding. "You're also a villain." His finger moved to a white puppy licking the rim of a cup on the table. The puppy looked up at him and barked twice. Wein's face suddenly changed: "What!? I'm a villain too!?" This book is also known as: 《The lighthearted comedy of holding a villain script but falling into love with the protagonist. Did I get something wrong?》
