I Broke the Npc's Heart

Traveling through the medieval dark slashing game, William, who is familiar with various poisonous spots in the world, has become a country knight outside the protagonist's group. "Since I'm not the protagonist, it means I have nothing to do with the plot, so it doesn't matter if I live freely like this!" The boy who gave up on the main mission and the protagonist group turned his attention to the NPCs who had fallen into miserable situations for various reasons in countless games. Non-player characters (NPCs) who died from assassination, poisoning, cave killing, humiliation killing, and imp killing. "How can we make the same mistake again!" In the face of living death, William could not remain calm. NPCs who are very popular among players, but ultimately meet tragic endings. In this life, I vow to save the NPC characters in the game and create a world where all NPCs can be happy. "There must be a very tragic reason for a kid of that age to live so desperately..." It's just... Why do the NPCs look at me with such sad eyes?
