When Aihara Ame was a high school student in Nagasaki, she wasn’t confident in herself due to her past. Asano Taiyo was a student attending the same school as Aihara Ame. He was the only person who talked to her brightly. With him, she was able to see her life positively for the first time in her life. She had feelings for him. After her graduation, she went to Tokyo to fulfill her dream of becoming a patissier without telling Asano Taiyo about her feelings for him.

After 8 years, she returns to Nagasaki. One day, she meets Asano Taiyo, whom she has never forgotten, and is elated to see him again. An accident soon occurs, and Aihara Ame falls into deep despair. A man appears in front of her and introduces himself as a guide from the afterlife. He tells her that if she gives her heart to him, he will make a miracle for her.
