Is it an Undertale fanfic, a Chinese AU? Legends of the Day? The Frozen Throne - the personal story of Baldwin's character
You can start reading directly from the second volume, but if you are afraid that some things will be a bit confusing, it is still recommended to start reading from the first volume.

Concept: The growth process of Frozen City?
