The game is set at a private high school in a regional Japanese city. At the beginning of the story, the protagonist finds himself in a classic “harem situation,”
surrounded by three charming heroines:
the seemingly unattainable Student Council President, a caring childhood friend,
and an approval-seeking “circle princess” underclassman. However, this is not an ordinary visual novel. The player is given exactly 100 days. or get cucked HARD!!!

Within this limited period, you must carefully manage the protagonist’s daily schedule,
and improve his stats—such as Intelligence,
Charm, and Toughness through studying, physical training, and other activities. When confronting overwhelmingly powerful intruders,
the protagonist’s abilities will become the only shield capable of protecting the heroines.
