What are some of the best story payoffs you experienced?

Mine:

Mayuri's ending in Steins;Gate My Darling's Embrace: As one of the rare Okabe/Mayuri shippers, finishing my S;G experience with this is one of the best story payoffs I experienced.

Tomoyo After true ending: Very heartbreaking and IMO much better than the canon Clannad After Story ending. If I have infinite money, I'll have an anime produced out of it.
