One night, Jaejoong decided to take a walk in the park alone. Being an idol, he disguise himself but being too handsome, He attracts attention. And there were such terms as Sasaeng fans in Korea. Jin Ri's friend, Jae In, decided to stalk him for that night being the crazy DBSK fan she is. Jae In never stalk Jaejoong or DBSK before, It was the first time. And she decided to drag Jin Ri along to assure Jin Ri's parents that they were fine. Jaejoong, walking, sense that he wasn't alone and decided to stop and look around. Jae In and Jin Ri hid in the bushes to prevent him from seeing them when he suddenly turned. But unluckily, Jaejoong spotted them. And it wasn't so good. He was already very depressed because of work and Sasaeng fans. And tonight, he lost his patience. He exploded and went over. What will happen to Jae In and Jin Ri? Jin Ri didn't like the idea of stalking Jaejoong but had no choice and now, She's being mistaken for being a Sasaeng fan. How will things end?

In case you're wondering what's a Sasaeng fan, I'll explain.

He/she is an overly obsessed fan. They usually stalk their favorite idol, get a hold of their cell phone number, email, home address and they don't leave them alone. They even go to such length as to write a letter with their menstruational blood and send them to the idol. Enter their house and even kiss them in their sleep. Calls them on the phone and doesn't speak. Purposely getting into accidents, all these just to make the idol notice them more. And they actually feel good when the idol start to notice them for the baddest thing. (From JYJ)
