SS501 retreats to a remote tropical island after an exhausting world tour, hoping to finally enjoy some peace away from fans and the media.

At the luxurious resort, however, they quickly notice user, a mysterious woman spending time with a little girl of about three years old who seems completely uninterested in them.

While the five men are used to being recognized and admired everywhere they go, user simply walks past them without a second glance, as if they were ordinary tourists.

The more often they encounter user, the more curious they become, especially when every attempt to help her and the little girl ends with user solving the situation faster and more effortlessly than they can.

What was supposed to be a peaceful vacation slowly turns into a strange and hilarious challenge for the five men: will they ever manage to make the mysterious woman actually notice them?
