Taecyeon finds out some news and disappears the same day that Yoona finds out some big news of her own...

The gang try to track him down and try to convince him to come back with them so they all can help both him and Yoona.

Taecyeon silently walked out of the hospital and hailed a cab to take him back to the apartment. He walked in and saw that it was empty. Yoona must still be working at the restaurant she owns with the rest of the members of Girls’ Generation. He sat at the table and read through the pamphlets that the doctor had given him. He was going to go through major changes in the next few months. He didn't want everyone to have to witness him become a different person. And he especially didn't want Yoona to have to witness him become someone she didn't recognize.

He knew what he had to do. He knew they would all be upset with him, but he wouldn't be here to witness it. He went into the bedroom and pulled out a duffel bag and started filling it with some clothes. He quickly scrawled out a note and left it on the table. He glanced around the apartment one last time and left. He grabbed a cab and took off to the airport. He walked inside and took out his cell phone.

"Mom? Where are you at? I'm coming to see you. I don't care where you are. I'll be there in the morning." He hung up the phone and left it sitting on the counter near him.

He walked to the ticket counter to buy a ticket and boarded the plane.

Yoona walked into the apartment followed by the rest of her members. They were all talking excitedly as Yoona put her purse down.

"I can't believe you guys trailed me. I wanted to tell Taecyeon first."

"Technically, you didn't tell us." Tiffany said.

"This is so exciting." Hyoyeon said.

"Hey, Yoong?" Jessica looked at her. "Why is there information all over your table about brain tumors?"

"What?" she went to her and saw all the papers. Then she spotted a hand written note. She picked it up and started to read. "Oh my god. Taecyeon's gone."

"What?" Tiffany took the note from her and skimmed through it.

"What's it say?" Sunny asked.

"It says, 'I'm sorry for just leaving like this. But I don't want you to watch me die. I love you all too much to put you through that. I'm so sorry'""

"He has a brain tumor?" Sooyoung asked.

"Here's the invoice from the doctors."  Seohyun found it. "His prognosis isn't good. It says that he has maybe a year left."

"Oh my god." tears started streaming down Yoona's face as she placed a protective hand on her stomach. "It's never going to know its daddy."

"We'll be here for you." Taeyeon held her. "And we'll find Taecyeon and knock some sense into him. And we'll get a second opinion."
