Working Holiday

On a summer day, a fifth-grade boy named Susumu unexpectedly arrives in front of former biker gang member and now host club host, Okita Yamamto, claiming that Okita is his father! Concerned about being a negative influence on his son, Yamamto changes his life to become a daytime working parcel delivery man. However, being a father proves to be more challenging than it appears as Yamamto faces difficulties in becoming a positive role model for his son.
