Nagasaki wrote the adapted screenplay for the movie, which is a remake of Jin-ho Hur's Christmas in August (8-wolui Keuriseumaseu). The movie's principal cast is as follows: Masayoshi Yamazaki (he also scored the movie), Megumi Seki (she plays Kazune Saiki in Issei Oda's live-action Warau Mikaeru), Hisashi Igawa, Naomi Nishida, Kôji Ôkura, and Naho Toda.
