Poison Arrow

Can you solve this monstrously difficult arrow sudoku?

This is the first puzzle I am making in a series of arrow sudoku puzzles that require set theory to solve.

If you are not familiar with set theory, watch Simon explain it.

Rules

Standard sudoku rules apply.

Numbers along an arrow sum to the number in the connected circle.

Digits on thermometers are strictly increasing from the bulb to the tip.

Solve the puzzle at https://f-puzzles.com/?id=yjpn4ocy

Solution code: row 1 and row 2

That first half was quite crazy, showcasing lots of intricate yet surprisingly beautiful deductions that follow right after the initial idea. Also, that thermo in row 3 helped me greatly to finally achieve the needed breakthrough. :)
(I feel like without that clue, the solve might not flow as well)

A great problem, worthy of five stars, I almost missed it. Thank you author, please continue to make. It is definitely not a poison, as long as you find the right way to break in, you will be very comfortable afterwards!

Thanks for trying my puzzle! For anyone who is stuck, I wrote up the first few deductions into a google document.
