Hirayasumi

Hiroto is a 29-year-old part-timer without a care in the world-no troubles, no lovers, no stable job. Twice a week, he visits the house of an elderly woman he met on a whim to share a meal with her. One winter, she suddenly dies, leaving the house to Hiroto. Three months later, Hiroto's sensitive cousin Natsumi comes to live with him while attending an art university.

Natsumi blunders through her self-introduction at art university and is convinced she blew her only chance to make new friends. Meanwhile, Hiroto hangs out with his old high school friend Hideki Noguchi, despite his concern over Natsumi's sullen mood. After some celebratory news, Hiroto's trip home is interrupted by a sudden phone call from Natsumi…

Yomogi Tachibana visits a fish pond where Hiroto works part-time. After watching her make busy phone calls while fishing, Hiroto ultimately does something to offend her. This bothers Hiroto until his friend Hideki brings high-quality beef on his way home from work. While the two of them enjoy a meal at Hiroto's house, Natsumi grumpily secludes herself in her room.

Returning from work, Hiroto runs into Natsumi at Asagaya Station. The latter has been skipping class due to her lack of friends and was wandering around town. Natsumi questions why Hiroto always seems so worry-free and his answer surprises her. Upon resuming class, she reunites with Akari Yokoyama, the girl who gave her water when she was drunk.

One day, Hiroto and Natsumi leave their tiny house to watch a movie. At the station, Hiroto encounters the woman he offended at the fish pond, Yomogi, whose values and pace of life vastly differ from his own. This makes her miss the train, and she becomes increasingly annoyed with him. Hiroto and Natsumi return home under a sudden rain to find a leak in their roof.

Hiroto is surprised when Yomogi is the one who arrives to fix their leaky roof. Natsumi notices the tension between them and laughs at seeing Hiroto lose his cool. As Yomogi works under the hot sun, Hideki arrives with a giant striped jack. The thought of sashimi puts Hiroto and Natsumi in high spirits, but…
