Kai POV

"We've arrived at the KBS building miss jung", I told Krystal who is sitting beside me in the passenger seat. "Don't call me that", I got a punch in my shoulder. Today is Amber's last Shake That Brass performace, since Krystal is schedule free today, she wanted to visit the llama of the f(x) family. It doesn't occur often that an idol promotes for such a long time. SM probably wanted to give Amber the chance to shine, yes that's probably the reason. We entered the KBS building passing by lots of rookie groups who greeted Krystal with respect. I greeted the 4Minute members, a TeenTop member and the INFINITE F members (I know they aren't promoting with Amber) who faced Krystal for a moment to talk with. I didn't know what they exactly talked about, but I heard some worried words about Krystal. "Are you okay now?", Myungsoo worried about Krystal. "I'm okay now, why do you ask now? I have been back to work since two weeks!", Krystal said angrily. "That good to hear Soojung!", Sungjong laughed. The smiles on the male idols' face didn't please me. I know Krystal is close to certain guys like Myungsoo, Taemin, Rain and Minho... Sometimes Krystal was to close. I would just stand from a distance behind Krystal and listen to some of their conversations. It's hard for me to endure and do nothing. Tons of male idols have confessed that their ideal type is Krystal. Whenever when Krystal was around these idols, I'd liked to shield Krystal from their sights. The stares at my girl, I hate it. "Anyong oppa, I have to go to Amber unnie. She'll get mad if I come late", Soojung eyesmiled to the three guys. I followed Krystal through the hallway. "Yahh what was that", I tapped Soojung on her shoulder. "What?", she asked. "Didn't I tell you not to behave like that around male idols or any men?", I whispered jeaulously, making no one around us able to hear. The girl in front of me froze on her place and looked at me. I pouted. "Kai, stop behaving like this, what if someone finds out. You know who I like...", Krystal said quietly. She flicked my forehead, making me wake up from reality. I didn't think straight, I should keep my feelings for Krystal out at these moments when Krystal and I are both working. After a short discussion we walked to the end of the hallway. Without knocking on the door Krystal opened the door with a white paper with Amber's name written on it. "PRINCESSS!!", Amber shouted out loud. "JONGIN OPPAAAA", Amber gave me a brofist. "Anyong Amber", I greeted. "Excited to see me?", Krystal -faced Amber on a friendly way. "Ofcourse I am excited to see my ice princess! Gomawoo for coming", Amber said. Amber looked at me and then at Krystal, and then smirked. "What's wrong?", Krystal asked nervously. "Unnie, can you please us alone for a moment?", Amber asked the make-up unnie to leave the waitingroom. "Yes, but hurry up, you'll have to perform later on!", the make-up unnie anwsered and left the room. "You tried to hide from me that you two are dating aren't you?", Amber asked us both. We were speechles for a moment. "Luna unnie and Sulli told you didn't they?", Krystal asked. "I wanted to tell you personally...". Amber puts her arm around my neck. "Hyung, you can take that ice-princess' character? I warn you that she might by too ice-princess- ish for you", Amber joked. "Yahhhh AMber!", Krystal screamed. I looked at Krystal, wondering why she called me her hyung since she's a girl. "She's a girl like that", Krystal said. "Don't misunderstand, I only call close oppas hyungs kk", Amber said. The door of the waiting room flew open. "Amber 10 minutes!", a man in black shirt said. "Yes", Amber anwsered. Just when the man in a black shirt left the doorway Mingjoon manager hyung walked in. I greeted him. "Hey how are you doing?", he asked. "I am fine hyung~", I anwsered. Minjoon smiled. "Amber come on, you have to prepare for your last s
