She is Convinced that her Half-Brother is a Girl Manhua

Title: She's Not My Brother! In a quaint little town, Lily lived with her half-brother, Alex. Alex always had a mysterious aura about him, but Lily couldn't quite put her finger on it. One day, while cleaning Alex's room, Lily stumbled upon a hidden box filled with wigs, dresses, and makeup. Shocked, she couldn't help but wonder if Alex was hiding a secret identity. As days passed, Lily became more observant of Alex's behaviors. The way he moved and talked seemed oddly feminine. Doubt gnawed at Lily's mind until she finally decided to confront Alex during a family dinner. With a trembling voice, Lily bravely uttered, "Alex, I know your secret." Alex's eyes widened in surprise, but then he burst into laughter. Confused, Lily questioned him, and Alex explained that he was merely preparing for a school play and had been taking acting classes. Relief flooded over Lily as she realized her mistake. She couldn't believe how easily she had been fooled by Alex's acting skills. The siblings shared a hearty laugh, and from that day on, their bond grew even stronger. Through this misunderstanding, Lily learned an important lesson - not everything is as it seems at first glance. With a little humor and understanding, even the most perplexing mysteries can be unraveled, bringing people closer together in the process.
