定職も恋人もいない、気ままなヒロト。でも、将来の不安はゼロ。そのお人好しぶりから、近所に住む年配の女性・和田花枝と仲良くなり、二人でほぼ金欠で平屋を購入する。そして、美大進学のために山形から上京してきた18歳の従妹・小林夏海と同居生活を始める。やがて、ヒロトの周りには、仕事や人間関係、漠然とした将来への不安を抱える人々が集まってくる。
Hiroto is a carefree spirit with no permanent job or girlfriend, but no worries about the future. Because of his good personality, he becomes friends with a neighbor, an elderly woman named Wada Hanae, and they buy a single-story house for almost no money. He then begins living together with his 18-year-old cousin, Kobayashi Natsumi, who has moved to Tokyo from Yamagata to attend art school. Before long, Hiroto finds himself surrounded by people who are troubled by work, relationships, and vague anxieties about the future.
