Clever construction, and not as easy as expected - 2* for me. Thank you very much for creating and sharing this lovely puzzle.

objective: how many candidate pairs can you stuff into a single sudoku?
looks much harder than level 1. no special rules, just a couple cages and arrows, how is this possible ?
