Ichika, a female student who grew up in a complicated family environment, was sexually abused on a daily basis by her mother's remarried partner, and before she knew it, she could no longer trust adults. Whether he knows about her background or not, Oshima, her manager, sees Ichika standing alone in a park at night and invites her to his home, crying, saying, ``I don't want to go back to her house...'' Put it away. She thought that she hated adults, but her state of mind gradually changed...and the two of them ended up crossing a line that should never be crossed.
