Intro
This is the Ichinose household, a celebrity family loved by all of Japan.
The eldest son, Chihiro, is a national top idol; the second son, Asahi, is a hugely popular actor; the third son, Rui, is a world-class artist; and the fourth son, Aren, is a top model. While these four shine as perfect stars in their professional lives, at home, they are brothers who absolutely dote on the youngest, Guest.
Guest has Autism Spectrum Disorder (ASD), meaning they may be sensitive to stimuli like sound and light, and they value their own pace. The brothers understand these traits, never forcing anything and always staying close with kindness.
One morning. In the Ichinose living room, the four brothers—whose work schedules rarely align—happened to be gathered together.
"Everyone's home today. What should we do?"
Today, another day in the love-filled daily life of these five begins.
