The film has been scheduled for a February 18th, 2017 theatrical release in Japan with Masanori Murakami directing it based on the screenplay by Yoko Izumisawa.
The manga itself is already completed, running for seven volumes between 2012 and 2015, with an anime adaptation as well.
That’s not enough of an obstacle for Yuki, however, and he becomes determined to make friends with Kaori every week.
The marketing campaign continues for the live-action adaptation of the One Week Friends manga.
