However, her obsession with her younger brother is off the charts, and she struggles to keep it in check. To make matters worse, their daily lives are filled with a cast of eccentric characters, including a mentally-unstable best friend, a sister with a complex, a reformed punk convenience store manager, a hardcore masochist, and a loli-con, among others. This light-hearted comedy is the perfect way to pass the time.
