In 1997, the rock band achieved fame with their debut single album Going. However, it subsequently broke up after the band leader Seigi announced that he will make his solo debut. Fifteen years later, in 2012, Seigi has already fallen out of the public eye, though he still clings on stubbornly to his outdated style of music. Only his agent and some die-hard fans are still willing to support him.
One day, three children who claimed that Seigi is their father suddenly appears. Two of them are siblings whose mother had recently died, while the other is left at home alone because her mother frequently runs away with her boyfriends. Although reluctant at first, Seigi takes them in and takes care of them. Over time, Seigi and the children start to bond after overcoming the many challenges that had come their way. Thanks to the influence of his children, Seigi starts to grow out of his selfish and immature ways, and starts to consider the feelings of his children and the people around him.
