@harperbows Apparently the guy broke his only mirror during his time of self-hatred, and it seems like there were no mirrors or reflective surfaces in the other world.
And frankly, this is one of the details you should pay the least attention to, considering the huge wish-fulfillment fantasy...
@zzmoonyzz I don't think that's why he chose to do ditch cleaning, that's what the others were deciding it was. He just wants to live a simple life, doing simple tasks. The problem is that he goes way overboard when doing them, and he's garnering way too much attention.
