Normal sudoku rules apply.
Digits may not repeat on the diagonal marked in pink.
Any adjacent pair of digits on a red line must include an odd and an even digit.
A clue outside the grid indicates that, in the row or column next to the clue, there are at least two adjacent pairs of digits which sum to the given value.
Solution code: Rows 1 and 4

Very cute. Parity pattern shook out pretty quickly just through experimentation (because there's only two possible relationships between the inner and outer heart), not sure if I was supposed to be able to use some sort of fancier sudoku logic for that.

Beautiful solve path. It took me a while to solve, but it was more than worth the effort.

Not quite as crazy as Intersections, but just as magnificent and fun. Thanks!

So sad Simon made one of yours yesterday. Could have been a nice one for the 14th.
Great puzzle, as always.

That was a lovely puzzle that flowed very smoothly. I loved the clues outside the grid in particular, those deductions were particularly satisfying
