While the current members of the pop groups Aomori and Distraction prepare for their Spain concerts, erotic romance writer Shaundra Yoshida must face another separation from her husband Ichiro while she makes a long-awaited journey back to the United States for the filming of her latest book. With a teary goodbye at the airport, Ichiro promises Shaundra that this will be their last separation because he intends to retire from singing at the end of the year to spend time with her and their twin boys Raiden and Ryoto. But even as he watches Shaundra leave, Ichiro's old jealousies flair because Shaundra will be staying in California with her bodyguard Dae-Hyun Choi, a South Korean martial artist who is also their sons' nanny.
