Memory and identity gap
The protagonist is Teo, heir to the François family, who often dreams of arguing with a young girl but cannot remember who she is. To learn the skills needed to manage the family in the future, he accepted his sister's arrangement to guide Aqua, who had just arrived at the mansion. The two gradually grow closer, but the differences in status between nobles and maids, along with Aqua's unspoken secrets, put obstacles to their relationship.
Characters in the mansion
Aqua works hard to learn cleaning, laundry, and cooking, hoping to become a capable maid. Senior Marine helps newcomers adapt to work and often jokes around; Fubuki is the protagonist's older sister, who manages the territory while their father is away and places greater emphasis on the family's future. The game places these characters in an independent fictional world, performed by Hololive members.
Opening and ending themes
The opening theme "Stay Blue" is performed by Aqua Minato, with lyrics, composition, and arrangement by Jin; The performers include drummer Yumao, bassist Mashiro Shirakami, and pianist Hiroshi Funatsu.
