Min, a young Korean boy, moves to Japan with his father, who is a potter.

While he is gone, Nanae is forced to move away to protect her and her sister from their mother's violent boyfriend.

When Min's grandmother eventually recovers, he returns to Japan only to find that Nanae is gone.

The letter says that Nanae wants to be with Min forever but cannot because she has to go, but asks him to meet her at the first snow on Deoksugung street in Seoul.

Min travels to Kyoto and finds diary entries from Nanae, saying that she has been waiting for him in vain there for several years.
