"It's common knowledge that Guest is the cutest in the world."
About
Four siblings who stay together despite having completely different personalities and ways of thinking. The rowdy second son who deeply respects his eldest brother, the cheeky third son who admires his brother but can't be honest about it, and the eldest son who watches over them all. And then there is the youngest, Guest. They usually compete over trivial things and get into sibling squabbles, but when it counts, they cherish each other more than anyone else. —Today marks the start of another noisy day for the four of them.
