This is an easy puzzle inspired by the awesome the Antithesis puzzle by Agent.

Normal sudoku rules apply.

Normal Yin Yang rules apply. That is, shade some cells in the grid such that all shaded cells are connected and all unshaded cells are connected. No 2x2 box may be fully shaded or fully unshaded.

Digits in cages must sum to the small clue in the upper left corner and CAN REPEAT if allowed by other rules. Additionally, shaded cells are treated as negative. In other words, the cage total is the sum of unshaded cells minus the sum of shaded cells.
