Everything starts on the birthday of Eun Jae’s dad. Eun Jae ran into Park Moo Yul, who is the 2nd baseman of ‘Green Dreamers’, when she is drunk. Eun Jae who is a fan of ‘Blue Seagulls’, starts a fight with Moo Yul who led the ‘Green Dreamers’ to victory. The next day, internet is on fire with the video called ‘Humiliated Park Moo Yul’. Because of this video, career of both Moo Yul and Eun Jae, who recently got a job as a bodyguard, are in danger.
In the end, they decided to put on a show against the public! They lie that Eun Jae is Moo Yul’s private bodyguard and the video was recorded when Eun Jae was giving a self-defence demonstration to Moo Yul. Like this, Eun Jae becomes real bodyguard of Moo Yul. It seemed like everything worked out just fine, but the problem is that they can’t stand each other’s existence..
