Synopsis
Siblings' relationship darkens into disturbing territory after parents' divorce, exploring twisted familial love and psychological trauma.
There is no bond stronger than the one between siblings. Yui and her brother Akira have always shared an unusually close relationship, one that has grown increasingly complex as they've matured. Following their parents' divorce, Akira finds himself thrust into a caretaker role, responsible for his younger sister's daily needs and well-being. As they navigate their new family dynamic alone, the boundaries between brother and sister begin to blur in ways neither anticipated. Akira struggles with feelings he knows he shouldn't have, while Yui discovers that her own emotions toward her brother are far more complicated than simple sibling affection. This dark psychological drama explores the dangerous territory where familial love can transform into something far more disturbing, examining how isolation and trauma can warp the most fundamental human relationships.
There is no bond stronger than the one between siblings. Yui has been the center of her brother's sexual desires ever since they were children. But in recent years, something in their relationship has changed. The divorce of their parents has forced Akira to pay more attention to Yui's well-being, take care of her on a daily basis, and assume the paternal role in their family. As the two grow older, Akira has taken notice of the physical changes in Yui—she is no longer the precious child he thought he knew. Unable to stop himself, he starts sneaking into her room at night, admiring his sister's body and pleasing himself to her. Akira becomes increasingly frustrated with the distance between them; but when Yui reveals that a friend from school has confessed to her, something snaps inside him. No longer restricting himself to mere daydreams, he actively has intercourse with his sleeping sister. However, unbeknownst to Akira, Yui remains wide awake during these nightly visits; yet, for some reason, is unwilling to stop him.
