Musume no Shinshitsu

Goto is a university lecturer who appears to have it all: a beautiful wife who works as an artist, intelligent and adorable children, and the picture of a contented household. Yet, beneath this flawless exterior lies a crumbling reality. By day, he is consumed by growing suspicions that his wife is being unfaithful. By night, his deteriorating mental state manifests in deeply disturbing nightmares, including one in which he engages in a sexual act with his own daughter. As his sanity slowly unravels, the boundary between his waking paranoia and his dark dreams begins to blur. The fragile illusion of his family shatters completely when Goto returns home one day to discover his daughter weeping inside her vandalized bedroom. Immediately convinced that his wife is responsible for the destruction, he resolves to do whatever it takes to shield his precious child from further harm. Driven by obsession and a fraying grip on reality, Goto's desperate need to protect his daughter plunges their household into chaos. What follows is a dark, unsettling descent into a morally bankrupt domestic thriller where trust is nonexistent and hidden sins threaten to destroy everything.
