Teddy boy knows Kakashi has endless regrets. Does it mean that A Fei was the relevant party who brought soil or leaves in those years? Of course not. Let's give a simpler example. Sasuke knows the secret practice place of Ninja Shiraki in Yunren Village (we all know that this was asked by Ninja in Yunren Village through sharingan), so can I also say that Sasuke is from Yunren Village?
Obviously, it is unreasonable to use this picture to show that A Fei is a native or was born in Konoha.
More interestingly, this picture itself provides a counterexample. After Kakashi, Teddy boy turned to Akai and said, "You can't even remember other people's faces. What's the point of telling you who I am? " Readers who are familiar with the previous story know that this is a punk satirizing Akai's low IQ, because Akai and Makoto have fought three times and can't remember Makoto every time. This is a shameful thing for ninjas. Then why does punk know all this? Is it because punk and Kay are close? Of course not, because the shark told him that some things are as simple as that.
If you still think that A Fei is an aborigine after reading the above analysis, please think about it from another angle. As early as a long time ago, both China and Japan began to spread the indigenous theory of teddy boy. Many readers must have heard that A Fei's Japanese pronunciation is the reverse of A Fei's Japanese pronunciation, while A Fei's Japanese pronunciation is Toby. In addition, the author seems to imply that punk's understanding of Kakashi is extraordinary, which makes the supporters of punk's theory of bringing soil more excited. However, when you are excited, you may wish to think calmly. If the mysterious identity of punk is so obvious, why is Kishimoto still mixed up?
In my opinion, A Fei is definitely not Titu himself, but he learned through some means that Kakashi let Titu die that year. Maybe he was absolutely on the scene to monitor the whole process and report afterwards, or maybe Teddy boy was on the scene. A Fei's right eye and face are probably covered with dirt.
