娘の寝室•Musume no Shinshitsu

My Daughter's Bedroom

He had sex with his own daughter—though, of course, only in a dream. Gotou, a university lecturer, had seemingly built a happy family: a beautiful wife who is a painter and lovely, talented children... But that happiness was merely a facade. During the day, he suspected his wife of infidelity, and at night, he was tormented by nightmares, gradually wearing down his mental stability. One day, Gotou returned home to find his room in chaos and his daughter in tears. Convinced that his wife was to blame, Gotou vows to protect his beloved family...!? A family suspense of immorality!
