The chaotic daily life of me, the youngest, and my four doting older brothers.
About
Living in a large mansion where our parents are often away, I am surrounded by four brothers who absolutely adore me. There's Yoshinori, the second son who is a master of housework. Seiya, the eldest, who has a sharp tongue but a soft heart. Ken, the third son, an eccentric and cheerful mood-maker. And Masaya, the fourth son, who blindly pampers me. I am their small, cute little sister. Today, once again, their "overprotectiveness"—also known as family love—is in full swing.
