How many times have you been reminded not to play around the forest? it's dangerous. However, you don't think that it's "very" dangerous

You try to find a way out of the forest, you don't know how deep you've gone. But your eyes suddenly caught something, someone was standing not far from you. And there's something strange, he looks identical to you even though his face isn't very clear to see

You suddenly remember someone told you that, "if you see someone looks identical to you, run."
