Oasis

Shizue Kitade divorced her husband and left their son, Tsutomu, behind. Years later, she returns to her former home, hoping to reconnect with the family she abandoned. But her homecoming is far from warm: Tsutomu, now a young man, has harbored an obsessive fixation on his mother since childhood, shaped by a hypersexualized upbringing.

As Shizue tries to rebuild their relationship, Tsutomu's desires escalate, pushing the boundaries of their bond. The tension between them grows until Tsutomu goes too far, forcing Shizue to confront the dark consequences of her return and the twisted nature of their connection.
