I think the show should end at 30 episode. The last few episode felt like very draggy.
I also think the ending part should be at least 1 full episode.
The last episode was still the leads trying to resolve some issue and the ending ending was done in like 15-20min.
So some episodes felt like there's fillers to fill the time because they wanted to end it at 36 instead of actually needing 36 episode. I think it would have been much better if problems were all resolved in the episode before the last and just give us the last episode of the ending like what happens with the character after they resolved their issue. I'm trying to write this without putting in any spoilers It's quiet difficult to explain without actually mentioning some spoilers .
