Kono and Adam might just be Hawaii Five-0's top sweethearts. They'd already been through thick-and-thin before their wedding vows. Even their special day and honeymoon were interrupted (by a nuclear threat and kidnapping, respectively). Fortunately, they've always had each other to rely on.

Catherine Rollins has been an on-and-off love interest of Steve McGarrett's since the series began, but disappeared from his life when she chose to stay in Afghanistan to help on a humanitarian mission. She returned on the eve of Kono and Adam's wedding, much to McGarrett's delight, but decided to leave again just before he could propose.

Rachel and Danny

Danny and Rachel's relationship began while he was a cop in New Jersey. The two divorced there, but Danny may not have ended up with Five-0 if not for her decision to move to Hawaii.

It seemed Rachel might be moving on and she even tried to move to Las Vegas, but after having a son she eventually reveals to Danny that he's also the boy's father.
