Chika Tokorozawa, the daughter of a pet shop owner, seems unable to get away from her brave but stupid dog, Rin Tin Tin (played by famous Japanese comedian Jimmy Onishi). The dog seems to be in love with her owner to the point of obsession, but his dream of getting with the girl is thwarted over and over again by everyone and everything around him, including his very uninterested owner. Based on the ecchi comedy manga by Maki Ootsubo, originally published in Weekly Young Sunday.
