Daisuke Suwa is a reserved high school student living with his widowed mother in a remote rural town. At school, he acts like a womanizer interested in every girl except the shy Hinako Aikawa, whom he claims is pretending to be a "sweet virgin." One day, Daisuke gets caught up in an argument between two of his admirers and seeks shelter in a church. He hides inside a confessional, only for Hinako to enter and mistake his voice for that of a priest. She asks him to listen to her confession, to which he has no choice but to comply. Hinako reveals that she was sexually abused by her stepfather while in junior high school, which led to her giving up a baby boy for adoption. Now aware of her secrets, Daisuke can't help but empathize with her. However, as the pair become closer, can his compassion turn into something more?
