A tender, pure love story unfolds over the Water Lily Peach.

Riko, who is about to enroll in high school this spring, is worried about the growth spurt she is going through. She was sickly as a child but suddenly gained perfect health, and her height and body matured at an unusually fast rate. While it should be a blessing, she has complicated feelings toward the sudden change... Riko had been nurturing a mysterious Water Lily Peach left behind by her older brother, who is no longer at home. She follows the notes left in her brother’s handbook, and the day it finally bears fruit, she encounters a spirit boy named Seiji. Despite being over 200 years old, he takes on the appearance of a young child and there seems to be a mysterious reason for his stunted growth... Riko learns that the Water Lily Peach is a panacea capable of curing any disease or curse, that Seiji was its original owner, and that he is here to take it back.
