Yamazaki Kento continues his streak of live-action youth romance adaptations with One Week Friends, based on Hazuki Matchas popular manga. Directed by Murakami Shosuke ( Threads of Destiny), the film stars Yamazaki as high school student Yuki who reaches out to loner classmate Kaori, played by Kawaguchi Haruna ( Say "e;I Love You"e;). Yuki notices that Kaori seems to not have any friends & tries to get closer to her. Kaori, however, reveals that she has anterograde amnesia, a condition that causes her to forget any new friends after one week. Since her memory resets every Monday, she chooses to keep to herself. Undeterred, Yuki sets out to befriend her anew every week.
