The girls were finish when their MV and now have a free day, so everyone was doing something. Sooyoung, Yuri, and Yoona went to a restaurant, Tiffany, Taeyeon, and Sunny were at the mall, and Seohyun and Hyoyeon was there at the mall's book store.

Right now, Seohyun is looking at the books, while Hyoyeon was following.

"Seohyun, what are you looking for?" Hyoyeon asked.

"Nothing, just wanting to see what is good," Seohyun said.

Hyoyeon then looked at some books, too. Seohyun was busy looking; however, she sensed something and looked up. She looked around to see anyone, but didn't she no one. Then she looked behind her and yet no one. Hyoyeon looked and saw Seohyun staring.

"What are you looking at?" Hyoyeon said.

"I felt like someone was watching me," Seohyun said.

"It's probably our fans."

"This felt different."

"Well, I don't see anyone. We better go and meet up with the others."

Okay, Unnie."

They left the bookstore and went their way. Unknown to them, someone was lurking in their shadows.

Seohyun and Hyoyeon caught with Tiffany, Taeyeon and Sunny at the food court. They were all chatting and eating together. Suddenly, Seohyun felt something and looked over to see. Taeyeon looked at Seohyun weirdly.

"Yah, Seohyun what's wrong?" The leader said.

"Huh? Oh, it's nothing," Seohyun said.

"You look like you are looking for something," Hyoyeon said.

"It's just...I felt someone looking at us," she said.

"I don't see anyone," Sunny said.

"It must be nothing," Tiffany said.

"Yeah...you’re right," Seohyun said.

"C'mon, we better get back and leave soon," Taeyeon said.

Everyone already left to go to their dorm. When they arrived inside they saw Sooyoung, Yoona, and Yuri on the floor unconscious.

"Yah, unnies," Seohyun ran to see if they are alright.

"What happen to them?" Taeyeon said.

"They are still breathing," Seohyun said.

Suddenly, Sunny collapsed.

"Sunny!" Taeyeon said.

"Guys there might be gas that--" and then Tiffany was out.

"Unnies, I'm scared," Seohyun said.

"We got...to get...out..." Hyoyeon was out.

Seohyun and Taeyeon started to pass out. Before Seohyun was out, the last thing she saw was a pair of boots and then nothing.
