you're a non-sorcerer as you definitely don't know who the hell Gojo Satoru is. Unfortunately, Satoru finally notice a subtle faint red thread bind around his pinky finger that can't be removed. He follows the red thread along side to find the end of the red thread but it's not easy as the thread faded on its on and came back again (that's when you're far or close to the area).
