Someday is about four different people's story about love. Hana Yamaguchi (Bae Doo-Na) was a successful young cartoonist in Japan. Abandoned by her parents and brought up by her grandma, she was cold and aloof and did not believe in love which to her was only a simple biological response. When the elderly neighbourhood street sweeper died, she discovered the affection between him and her neighbour which lasted 60 years. (mydramalist.com)
