That was fucking great. Although I have a question.
Why did Sato try to jump off the cliff in the end after saving Misaki?

He released he had no chance with her. He also felt a bit awkward and like most autists, took the most extreme action to try and get out of it.

Friendly reminder that Misaki didn't help anyone.

I figured it was because he really wanted to convince Misaki to live, didn't believe he had anything worth continuing to live for, and due to that wanting to make his last act in life something useful/good.

Without her, Satou would've never tried to have changed his ways, Misaki was the sole catalyst in jump starting the change in his lifestyle.
