This one doijin where the name was something something syndrome.
It was about hypnosis abt how a guy hypnotized q girl into doing things.
The girl is fully aware throughout the deeds but can't do anything even after the hypnosis is lifted cause of classic blackmailing photos
This continues as the guy hypnotizes her in a daily basis and the girl just goes through with it until one day he reveals the hypnosis app was broken many days ago and she believed she was hypnotized while actually she did the deeds automatically out of her own will while thinking she had no choice.
