高橋直人（岡山天音）は弁当チェーン会社の正社員として働いている。上司の森田（皆川猿時）やパートの成美（しゅはまはるみ）たちとの間で板挟みとなり、事務処理は一手に担わねばならず、残業も多い。辞めたいなと何となく思いつつ、父親（遠藤憲一）からはプレッシャーをかけられ、辞める勇気もなく日々を過ごしていた。ある日、パートの面接に同い年の女性・青木華（飯豊まりえ）がやって来る。独身、一人暮らし、夢はなし。ちょっと不思議な雰囲気で「週休４日でお願いします」と微笑む華に、高橋は一目ぼれしてしまう…。
Takahashi Naoto , a regular employee of a bento chain, gets caught between his boss Morita and part-timers including Narumi . He has to handle the paperwork alone and often works late. Although Takahashi toys with the idea of resigning, he is pressured by his father and gets through the days with no courage to quit. One day, a young lady called Aoki Hana, around the same age as Takahashi, comes to interview for a part-time position. She is single, lives alone and has no dream. With a slight aura of mystery, Hana smiles and requests a three-day week, and Takahashi ends up falling in love with her at first sight.
