The mystery of who Amami is making a very specific kind of handmade chocolate for, and why, isn’t all that mysterious. But as always with Re-Kan, the emotional resonance, not the mystery or animation, did most of the heavy-lifting, and succeeded admirably.
Not only that, as we watch Amami’s activities through the lenses of both her living and dead friends, all of whom have fairly reasonable theories, I felt the episode kept things in doubt long enough for the final twist to have some impact.
Working with the info we’re given from the start, Amami is going to make a traditional Japanese sweet, the recipe for which she learns from the kindly wife of a grouchy old humbug who infests the park scaring the Valentines-crazed youngs away.
The episode staves off the last piece of the puzzle with the use of editing and camera angles to keep the wife’s status up in the air until Amami finally presents the chocolates to the husband, at which point we see he is a widower.
Yet again, Amami did a favor for a ghost who couldn’t do it herself: make chocolates for her still grieving, lonely husband. She also doesn’t disappoint the ravenous Yamada or her friends by offering all of them chocolates, so everyone wins!
When the grumpy old man is alone again, he polishes off the whole box of chocolates, and realizing his departed wife is still there beside him on some plane or another, thanks her, his heart having been lifted from the gloom. The final shot that tracks from him sitting alone on the bench to the shadows of both him and his wife, was quite lovely and affecting.
