Yoo Eun-Jae, a bodyguard, defends her father using her Judo skills and throws Park Moo-Yeol to the ground. When the Red Dreamers find out a video of the incident has hit the Internet they decide that to prevent the negative publicity they will hire Yoo Eun-Jae to guard Park Moo-Yeol.

For the ploy to work under media attention however, Yoo Eun-Jae must actually perform as expected, in close attendance to Park Moo-Yeol. Thus the story plays out with Yoo Eun-Jae and Park Moo-Yeol battling not only each other, but a sinister stalker out to get the infamous Red Dreamer star Park Moo-Yeol.
