I'm doing my 3rd rewatch right now. for the first two watches I skipped the final two episodes because I heard it's a massive bummer and there's a big implication that they're going to part ways permanently after they graduate. I'm not sure if I want to finish the final two episodes or not this rewatch... but there's always a possibility that if I don't I could get T-boned at an intersection and never be able to finish the series
