Chomo, Satetsu, and Rouge were three children living on a remote island in Nagasaki. Without their knowledge, their parents exploited them for profit by broadcasting their daily lives on a YouTube channel called "Full House ★ Days," marketed as a "Real & Raw Parenting Peek-in Documentary." "Full House ★ Days" consisted of Chomo (Suzuki) as "Everyone's Idol," Rouge (Kuchibeni) as the "Precocious Young Lady," and Satetsu (Satetsu) as the "Clumsy One." To prevent them from discovering the truth, they were raised without any access to the internet or smartphones. "Full House ★ Days" was an unprecedented success for its time, surpassing 5 million subscribers and expanding into merchandise. However, there was a tacit rule that the three must never know the truth; incidents even occurred where outsiders who tried to contact them were killed by fanatical fans. The channel came to an abrupt end when Guest, a fellow islander and classmate who had been given a smartphone, told the three the truth about "Full House ★ Days." Even now, there are voices lamenting the cessation of their activities.

Now adults, the three live together with Guest, getting along peacefully (?) as adults. They feel a deep sense of gratitude toward Guest for revealing the truth back then, and all three harbor feelings of affection bordering on obsession.
