Everybody dancing happily in the front of the Kim family, they heard his scream, nobody do anything, except for Yoona's friends, and Kai's friends. They run as fast as they could to the garden.

"SHE IS DISSAPPEAR? THAT IS SO IMPOSSIBLE!" Sunny yelled out, she doesn't believe in what she heard from Kai, she can't.

All of Kai's friends, Lay, Luhan, Chen, Sehun, Sunny, Jessica, Yuri, all of them, they don't believe in what Kai is saying, is he insane? They all saw Kai was with Yoona, Kai was holding her hand into the garden, so how can this thing happen?

All of this happen to Yoona happening too fast. Maybe Kai knows what happen, but as he said, she is dissappear! He is crying, crying his heart out. He hugs Lay, the one who care for him first when he heard Kai scream in the garden. The scream is not a normal scream, it is a scream of terrifying of something just happen, something happen too fast that Kai, he didn't have enough time to reacts to it. His friends and Yoona's friend, they all confused of what happened, they all wonder to know what happened when Kai and Yoona enter the garden. They all want to know why is she dissappear? How is she dissappear so fast like that? What cause it? Who did it? Is Yoona, some kind of wizard or a bad devil side? All of this questions come from their mind so rapidly, they don't understand it. They want an explanation for this.

They look at Kai, "Kai, are you ok? Sehun gently sit down next to Kai, put his arm around Kai's shoulder.

"I don't know. I don't know why this is happen." Kai looks at Sehun, hug Sehun.

Sehun was surprised at what Kai did, he never did this to hi, but this time, his girlfriend is dissappear, so he thought he should give Kai a comfort.

Chen sits next to Kai, pat his hand on Kai's shoulder, he feel bad for Kai. He, himself confused of what just happen. Yoona and him are close friends, they always talk about random stuff, of course he feel worry what will happen to Yoona. He look over his side, Luhan sits next to him Luhan also fel sad for Kai, he feel bad that he couldn't do anything to help Kai to get his gilrfriend back, if he has a chance, he will help Kai.

Yoona's friend, they all feeling down, they could just have a fun time at the party, but this happen so fast. Their precious Yoona is dissappear within just a few seconds, how can they not feeling down?

For a few moment of silence, Luhan speaks up "Ah, I know how we can get Yoona bakc!. After he said that, all Kai's friends, and him, and Yoona's friend bright up, "Really? How?" they all said it at the same time. "I know a very smart detective, his name is Taemin." Luhan said.
