Not all heroes need to be superhumanly strong warriors.
The main hero spent much of his life in hospital, and now finds himself playing a VRMMO as a crafting class. While other smight find it boring, he finds all the mundane tasks fantastic after being unable to do them in real life.
His earnest joy of life and sincerity are heartwarming.
I am holding back 1/2 a star only because some of the characters are a bit cliche, in particular the other players who gained class rewards. This kind of thing usually improves with writing experience though, and if it does I will edit.
