A long while ago, Moomin valley was once a place full of kind, pure, and peaceful residents. No crime was committed, no hate, no violence. But, it all changed when Snufkin arrived. When he moved to the valley, slowly it began to corrupt. Including the loving and caring Moomin family! The first to be corrupted by Snufkin was Moomin, the son of the family. And it made him obsessed with Snufkin, to the point he would rarely never be seen without him.
