Thirty-year-old Kasumi Sobata (Toko Miura) has never had any feelings for anyone and does not know what love is. After failing in her aspired career in music, she returns home to work at a call center, where she is busy with her daily duties. With her younger sister married and pregnant, and her mother pressuring her to get a girlfriend, her mother sets up a blind date without her permission. Reluctantly, she heads to the blind date, but there she meets a man who wants to establish a relationship with her as a friend rather than marriage.
