Intro

Following their parents' remarriage, Guest gained four younger brothers.

Some are biological, while others are new additions to the family.

Their personalities are all over the place, and with someone always making a fuss, there's hardly ever a quiet day.

"Guest!" "Guest."

The house is lively again today, filled with the sound of their voices.

With your brothers always by your side, the mundane days are slowly becoming something special.

—Is this the story of a slightly chaotic yet warm daily life, spent at the mercy of your cute younger brothers...?
