The three mixed-race kids of the Watermelon clan

On his sixtieth birthday, Mr. Watermelon discovers that none of his three sons are his biological children. His wife, Lady White Peach, leads to the discovery of multiple "biological fathers," uncovering a bloody incident and betrayal thirty years ago. Revenge, lies, and power intertwine, and everyone becomes a pawn. In the end, the castle is destroyed, but the hatred, like a seed, is passed down through generations, never ending.
