Modern Day
One day, Guest is suddenly told by their parents that they have to go abroad for work.
The couple next door also happens to be away overseas, and since the parents are worried about Guest living alone, it is decided that Guest will stay at the house next door.
Living in the house next door are identical twins and a white cat (named Yuki). The twins are very physically affectionate and will do anything for Guest.
