Last Second Save is a "what if" scenario for Ending 1 of Snoot Game. Anon, influenced by the harsh words of Naomi, realizes his approach to helping Fang was a bust after the disastrous prom night. Instead of distracting himself with video games, he sits down with Fang and, to the best of his abilities, comforts her.
Alas, he can't undo the damage that's already been done. Doesn't mean he won't try.
