The protagonist, Nobuo Sato, a humble part-time worker, stops by a park on his way home from work and finds a female student there.
Nobuo follows the student, Shiho Mononobe, and tracks her down to her home, where he devises a plan.
This is the beginning of a nightmare for Shiho.
The player controls Nobuo, setting up cameras in the house and completing tasks.
This cycle continues with a monitoring phase where Shiho’s actions are observed.
Household tasks performed during the intrusion can reduce Shiho’s fatigue level.
Shiho’s behavior patterns are determined by her fatigue level.
The system progresses through a week, divided into the beginning, middle, and end of the week. Weekends offer a wider range of actions and opportunities for interaction with Shiho.
As you interact with the heroine and progress through events, you will be able to attack Shiho during intrusions.
Erotic events vary depending on the location and situation in the room.
Also, just before the end of the day, there’s a touching scene where you play naughty tricks on Shiho without waking her up.
