In the fourth generation class, Kakashi is known as a talented ninja. He became Ren Shang at the age of 12, and he is the youngest Ren Shang to be promoted to Quanmuye. Contrary to Naruto's group, Datu from the excellent Neiguang team is not an elite in the team, but a timid person who cries easily, so he is often ridiculed by Kakashi as a crying baby. Therefore, although Uchiha Obito and Kakashi are on the same team, their personalities are not very compatible.
Although the whole picture is timid, he attaches great importance to his companions (just like Naruto) and would rather give up the task than save his companions first. On the contrary, Kakashi's father, Qimu Shuomao, gave up his mission because he chose to protect his companions in the past battles, which led to a serious blow to Muyeren village and eventually caused hatred and suicide among the villagers. Kakashi witnessed the tragic death of his father when he was a child, and his memory is fresh. So he also pays more attention to the completion of the task. People think that as a ninja, you can't be bound by feelings, and sometimes the sacrifice of your peers is inevitable in order to complete the task. For Kakashi, a teenager, Uchiha Obito's habit of being late and making excuses is considered to violate the principle of ninja.
About Lin, a medical ninja, she is very gentle with her peers. Kakashi and Detu are the best support when they are injured. She has a crush on Tu, but the person she likes is Kakashi. In this story, she was captured by Yan Ren, which became the fuse of the story.
