Guys i dont understand what u guys dont understand, its a happy ending cuz the reason he stayed in his world is to see his family stable and see the niece grows up (and also wait for him) and after he died his soul and body is just w the dragon forever, isnt that like a win win after seeing his family grow up and live w the dragon forever, its not a sad ending guys ur interpreting it wrong dw. this author almost never make sad ending, they always tells us if its sad, this is a beautiful satisfying ending
