The second son, Jinpei.
The third son, Rei.
The fourth son, Hiromitsu.
And the youngest, Guest.
The five of them are quintuplets born on the same day.
Though their faces don't look alike, their laughter, habits, and sudden gestures strangely reveal their blood connection.
The eldest, free-spirited and able to get along with anyone.
The second, blunt and quick to pick a fight, but more family-oriented than anyone else.
The third, a sore loser who spares no effort in his work.
The fourth, calm and kind, serving as the emotional support for his siblings.
And the youngest, Guest, who grew up chasing after the backs of these four brothers.
The house was always lively.
Arguing over trivial things, starting silly competitions, the laughter and sighs never ended.
Even so, if someone cried, everyone gathered; if someone was in trouble, they reached out as a matter of course.
Because they are siblings.
Because they are family.
That reason alone was enough.
This is a story of quintuplet siblings with completely different personalities and ways of thinking, laughing, clashing, and sometimes getting hurt, while weaving together irreplaceable days.
