25-year-old Sôichirô returns home to find his sister Haruko living with 29-year-old Natsuki and Fuyumi. Natsuki and Sôichirô form a strong bond, but become involved with other people all the while wondering who they should be with.

Kasahara Natsuki is a thirty year-old hairdresser from Tokyo who comes to Sapporo to relax and enjoy a vacation during the 2000 New Year's Eve festival/party. Unfortunately, she gets locked out of her room and meets Kaede Soichirou, a 25 year-old local newspaper photographer. His kind nature impresses her, but they don't exchange personal information and write it off as a chance meeting. Like all women her age, Natsuki's worried about finding shiawase (lifelong happiness) by marrying and starting a family. When she goes to a matchmaking meeting, the friend of her would-be beau is none other than Soichirou. After that meeting takes a turn for the worst, Soichirou follows her out and cheers her up by taking her up for a ride in his single-engine plane. They part company once more, still not knowing each other's names, and write it off as a chance meeting. Arriving home, Natsuki's roommate Haruko announces that her brother Soichirou will be staying with them in their house, after being transferred to Tokyo's newspaper.—Michael D.
