Join the Spy Family, I'm Aniya's Brother

Charles, a salty fish genius, traveled through time and became Aniya's brother. Dusk, who originally only wanted to adopt Aniya, decided to adopt him because of Ciel's good cooking skills. At this point, Ciel has successfully become a member of the spy family. But what everyone didn't expect was that Charles was not only superb at cooking, but also great at playing music, chess, calligraphy, painting, and singing. Dusk: I really wish he was my biological son. Aniya: My brother is very popular in school. He is a little star in the school. Joel: I like Charles so much. He is simply an all-around genius. I really hope he can be my teacher. Yuri: If he hadn't been a child, I would have suspected that he was a spy sent by the enemy country. This novel and its characters are purely fictitious.
