Serai Takagi

Devoted to becoming an international lawyer, Ayukawa Wakaba is full of ambition. Her hard work pays off when she lands a job at an international law firm, but to her disappointment, the first prestigious assignment that is given to her is to babysit the boss' 5 year old daughter, Hinata. Wakaba loathes kids and nursing, but unwillingly takes on the job as she is fixated on wealth and success. One day when she goes to a preschool to pick up Hinata, she meets a man named Yamada Sota. Sota is a man without higher education, wealth, or a future goal, someone that Wakaba absolutely cannot stand, the complete opposite of her ideals. Once again, contrary to her will, she ends up looking after Hinata and a few other kids along with Sota. Despite being exhausted from all the first-time experiences in child care, Wakaba begins to realize what is truly important to her.
