I think it should be regarded as an extra part of the Fast and Furious series. It is dedicated to the story of Han going to Tokyo alone after Gisele's death. After watching episode 6, including the easter eggs that follow, you should be able to see that the story in Fast 3 After Super 6, Han went to Tokyo alone after Gisele's death, lived in Tokyo, and accepted an apprentice by the way. I didn't expect that the brother of Owen Shaw, the villain in Super 6, would come for revenge, and he would be escaping from the villain in Super 3. Xiao Gao chased after him. Han of Han was hit and killed, creating a scene of a traffic accident, and then leaving behind the dom's necklace of crosses and a declaration of revenge. Then I recalled the Easter eggs of Super 3. Dom came to Tokyo and had a game with Han's disciples. It should be that Dom came to Tokyo to deal with Han's funeral after learning about Han's death. In this way, Super 3, which appeared suddenly, also has an explanation.
