Tear Jerker: Mahoromatic
The final two episodes of Mahoromatic: Something More Beautiful, with Mahoro self-destructing to save Suguru from an android attempting to kill him and later on in a somewhat Dystopic Future, an older Suguru is badly wounded and wishes that he could see Mahoro one last time before he dies (he lives though). Mahoro comes back to life, they stare at each other much like in the first episode, and they walk along a road, holding hands.
