In a Lonely Planet 2011 / 孤独な惑星 2011 / Kodokuna Wakusei

Mari lives a comfortable life as a single woman. She has a nice job at a company and resides in an apartment in the suburbs of Tokyo. A couple lives next to door to her. Mari can hear them argue or making happy conversations everyday. One night, when Mari comes back home, she sees her next-door neighbor sitting in front of his door and shivering from the cold. He locked himself out.
