Tatsuya Ishii won the JFF Special Award at the Pia Film Festival Award 2018 for Subarashiki Sekai. Here, he chases the concept of true love through the self-documentary format as he revisits time spent with an old lover. They had been dating for two years and she was in a mental ward of a hospital after the breakdown of the relationship. Ishii recorded their relationship while together until it got too bad. Then, one day, after a call from her, he visited her house with a camera in hand and talked to her to find out she had lost two years of her memory.
