Rules:
Normal sudoku rules apply.
Shade some cells in the grid such that all shaded cells form an area of orthogonally connected cells and all unshaded cells form an area of orthogonally connected cells.
No 2x2 area of cells may be fully shaded or fully unshaded.
If two shaded cells are orthogonally connected, the digits in them are consecutive.
Clues outside the grid show the sum of the digits in all shaded cells in the corresponding row/column.
Cells with a circle have an odd digit.

Quite incredible that a Yin Yang hybrid with the consecutive shaded cell constraint can exist, let alone be such a pleasure to solve!
