~Siwon's POV

Yoona doesn't care that Tiffany kissed me and I don't understand!

"Siwon. Can we talk outside?" Sooyoung asked me.

"Sure sis." I followed her outside the room.

"Siwon, I think that accident that happened is causing Yoona to forget about feelings that she feels before." Sooyoung whispered.

"Sooyoung. Stop it! You know that I am not falling for her! And she is just my fri---."

"No Siwon. I have a feeling that you're falling for your one and only bestfriend."

"Ok. Sooyoung you got me! I can't love her having a girlfriend."

"I know. All you have to do is..."

"Don't teach me Sooyoung! I know exactly what to do."

Then Tiffany got out of the room talking to somebody on the phone.

~Tiffany's conversation

"Honey, let's meet in the hotel later, by the way Siwon's staying in the hospital for his best---." She didn't continue.

~End of conversation

"What is this?!" I got her phone from her ear.

"Siwon. It was just my mom."

"Anniyo!"

I listened to the voice and it was a guy.

"We're over." I told her.

"Siwon..." She added.

I went to Yoona's room leaving Tiffany and Sooyoung.

~Outside the room

"Why are you cheating on my brother?"

"Sorry, my sister to be." She tried to be friends with her.

"I don't care about you!"

Sooyoung pushed her off and went to Yoona's room.

"Where's Tiffany?" She asked.

"She's outside."

"What did you do to her?" She asked me.

"Yoona, Siwon and Tiffany broke up Tiffany has been ch---"

"Anniyo! Get out of this room! She's a good friend!" She demanded us.

"Yoona!" I calmed her down.

"What are you talking about?! Tiffany is a good friend." She shoved me off.

"Anniyo Yoona, you got the wrong idea! She cheated on your bestfriend."

"Moeo(What)? She cheated on my bestfriend? Who is my bestfriend? But my only friend is her."

"Siwon is." Sooyoung told her.

"Siwon? Who's Siwon?" She pretended.

"I'm Siwon." I showed her a sad face.

"What's your surname?"

"Choi."

"You have the same surname as hers?"

"Neh. We're twins."

"Twins? I have never seen you before!?" She really lied.

"Yoona, are you joking me? Remember.. We were really bestfriends and hoped to be friends forever?"

~Flashback

"Siwon. I will be your bestfriend forever and I promise to be friends with you forever!" Yoona smiled at me.

"Neh." I answered her.
