From [MangaHelpers](https://www.mangaupdates.com/groups.html?id=1011): The Kemuyama family has just moved into town. From the outside, they seem ordinary. The family consists of a breadwinner father, a chubby mother, a teenage daughter Tara, and a video-gaming little brother Kemuo. What no one knows is that it is all an act. These four people aren't even really a family; they are four complete strangers. They were hired into their respective roles by a mysterious group they know only as "Tako-Pon." They're supposed to behave just as a normal family would, and to avoid discussing their individual pasts. When some of them bend the rules of the contract a little, letters of admonishment from Tako-Pon begin to arrive, making it clear that they are under very close surveillance. These letters eventually vanish, leaving no evidence behind. What is Tako-Pon and what does it really hope to gain from these people? [tethysdust]

Eighteen-year-old Ichimaru Kotaro moves into a rundown apartment in a shabby complex, anxious about living alone for the first time. Akiko Ikuno, who lived in room No. 8 for two years when she was a student, is upset that Kotaro, who moved into the same room, did not take good care of the place, and she decides to take over the closet. From that day on, they started living a strange cohabitation life together. (Source: eBookJapan, translated)
