Kuroi, dumped suddenly by his girlfriend after five years together, decided to get out of the city filled with memories as soon as possible and work at day labor sites in an unfamiliar town. There he met his boss, Fujiba, who was tough and stern. One day, while being confronted with his own helplessness, Kuroshi fell asleep at the worksite after working late into the night and was found by Fujiba. He ended up staying at her place for the night. There he learned that she was a single mother raising her daughter alone. Blacki, who had never seen such motherly kindness and attentiveness on the job, gradually became drawn to Futaba.
