Nankuru Nee-san

Issa Kinishi is a young man defined by his excessive worry and determination to remain entirely harmless and inoffensive. His carefully controlled life is disrupted when he encounters a beautiful, tanned, and enigmatic woman who lives without regard for modern conventions. She uses a smartphone with a cracked screen, dines at restaurants regardless of their online ratings, and cooks curry without concern for staining her clothes. Her unconventional nature captivates him so completely that he finds himself inadvertently stalking her.
