What is the relationship between Nakamori Aoko, Koizumi Akako and Bai Matan?

Jet Fight is Kidd's true identity, and Nakamori Aoko and he are childhood friends (both like each other and refuse to admit it ~). Nakamori Aoko's father is a policeman who specializes in catching Kidd (he will never catch Kidd, but he is still persistent ... so your daughter's boyfriend is ~). Qing Zi hates Kidd because of his father. He also suspected that Kuaidou was Kidd, but he was confused by Kuaidou ~

Koizumi Akako is similar to a witch. In short, boys all over the world like him (... it's too exaggerated orz)-except for playing fast, so she hates playing fast (mm-hmm, I hate it because of love ~ I put it down later). She knew it was Kidd through divination or something-but it was hard to admit it. Later, she helped him in danger. She likes to play fast, but she moves quickly.

Bai Matan, a detective who transferred to the Fast Fight class, regarded Kidd as his opponent. Later, through investigation, it was determined that Kuaidou was Kidd. Of course, it was successfully mixed by Kuaidou ~ (thanks to Hiroko), well, forget it. Anyway, it's useless to continue to doubt Kuaidou, because he can't catch it ~!

These four people are all classmates.
