This is a revenge article, somewhere between Detective Conan and Magic Kaito. There is no cp. Please watch a short clip:
School had just ended, and Kuroba Kaito and Nakamori Aoko were walking on the road... The two of them were smiling playfully. Suddenly, Kaito's phone rang. Kaito quickly picked up the phone, and two words appeared on the phone screen: Mom. Kaito quickly picked up the phone and said impatiently: "Oh? Mom, are you okay? If nothing happens... Do you believe I will shoot you with a poker gun the day you come home?"
A female voice came from the phone: "Boy, you are so cool! Do you believe I will tell Qingzi all your weaknesses?"
Kaito immediately begged for mercy: "Okay, okay... What's the matter with you calling me?"
The female voice said again: "By the way, don't talk nonsense. You will pick up your brother at the airport in ten minutes."
Kaito smiled and said, "I thought you were calling me about something, but it turned out to be this. Ah! Brother? When will I have a brother?" Before he could finish his words, the other party hung up the phone. Kaito was walking on the road and thinking: Why did a younger brother suddenly appear? When did I have a brother? Aoko gave Kaito a violent shudder with his hand, and said angrily: "Hey, Kaito, what are you thinking about? Why are you so dazed?" "Oh, it's okay, it's okay, I'm just thinking about things." Kaito answered eagerly, and Aoko asked, "What are you thinking about? Tell me."
