As his curiosity deepens, he wants to move beyond observation and get closer to the sisters.

The current build is v1.0.1, dated August 7, 2024, and development is ongoing. It runs on Windows and is available in an English fan translation. The scenes are censored with mosaics. The story content highlights adventure, harem, and male domination themes.

Developer's description

Tired of city life, our protagonist, Cameo (name can be changed), moves to the countryside and notices a mansion that seems out of place in his small town. When he finds out that two beautiful sisters, Manaka and Lenka, live there alone, he is drawn to them and spends his days taking candid photos of them from afar… One day, he witnesses the moment when the two leave the house. Watching them leave from afar, he realizes that he has forgotten to lock the door. Tempted, he sneaks into the mansion and, on a whim, borrows the spare key that was hidden there. Now that he can enter the mansion freely, he begins to spy on the couple’s lives with a hidden camera… As he does so, his desires no longer satisfy him with candid photos, and he begins to want to get closer to the two… What will become of the protagonist, Manaka, and Lenka?​

This game has really good art and the concept of exploring the house to get new information on the girls is good But other than that the game has a terrible execution, the fact that you only get 1 camera…
