It's very good it's kinda refreshing where other animes the mc whose known as demon lord are to fight to save the world and pursuing their dreams but this anime is about to change one's life who never seen happiness to show that happiness to feel new feeling and excitement where she never have experienced before
What makes us more happy than giving oneself or showing the happiness that they have never seen
To make someone life a beautiful and colourful who oneself experienced only black and white
