I don’t know about time traveling- because you move forward and backward. With this plot- they (Teach, Guwon, the town and inhabitants) are stuck in a loop. I think Teach needs to prevent Guwon from dying to break out of the loop. If you ever saw the movie Ground Hog Day-I think it kind of like that. The next chapter is going to be interesting- does it continue from here since Teach didn’t die from the fall (it looks like all previous versions did)- so he is going to have knowledge that his previous versions of himself and Guwon did not have- or will there be some other occurrence. Maybe there will be a new set of Guwon and Teach if the surviving Teach returns to town. So many possibilities

Is this some time travelling stuff and then if they die, they just resurrect? Oof, it's intriguing but my brain easily gets confused when the plot includes alternating timelines @-@ Probably just let this marinate for some time.
