It's been 4 months Krystal works as a babysitter to Tae Oh. She was awkward with the surrounding and now she is not anymore shy and feeling weird. SM Entertainment also knew about her and her relation with Mrs. Lee. So, she can easily come to SM Entertainment if there something about Tae Oh and Kai. Talking about Kai, they are now more closer and no more awkward. They can tease each other comfortablely without being shy. They also can express each other feelings very well as a good friends. They gived themselves a name called KaiStal. But, they still need to be caution since fans are not yet knowing about Krystal who was Tae Oh babysitter. 

"Krystal... can you bring along my perfume!" said Kai. He is so in rush. He suppose to be at the event now. 

"Which perfume??!!" shouts Krystal. 

"Hugo Boss! I really in hurry! I need to go now!" shouts Kai from the living room.

"Yes... You will be more handsome than Appa!" 

"Appa is a fatty bear! Hahaha!" 

"Whoahhh.. you are so in my side! Kaja! we need to be faster before the ceremony starts!" said Krystal. 

After done everything, Krystal brings Tae Oh to the Grand Hotel which was the place of the award held. EXO will be performed as the closing part. Kai wants Tae Oh to see him performed. Tae Oh just relax in the car while Krystal who the one that full of nervous. Suddenly her phone rings. 

"Nae...." 

"Babe, where are you? Kai keeps asking you to be faster." exclaim Mrs.Lee. 

"I am on my way with Tae Oh. Noona... where should I park?" asks Krystal. 

"You park at the groundfloor. I'll be waiting you there to pick up Tae Oh." said Mrs. Lee. 

"Then what about me? What if people notice me? Yahhh!" 

"Just covers yourselves. Don't worry!" 

"Noona I'm scared if there's a fans who notice me. Oh My God! I don't wanna be bashed!" Krystal panic. Tae Oh stares at her. 

"Yahh! Don't be to overthinking, just cover yourselves and relax. Plus, Kai said she wants you to come home with him after this event finish." said Mrs. Lee. 

"Then, how about my car??" 

"I will bring it." 

"Nae.. arasso.. wait there! I'm on my way!" said Krystal and hang off. Tae Oh still look at her weirdly. 

"Wae..?" asks Tae Oh. 

"Aniya.. I'm fine.! Aigoooo... my Tae Oh is so handsome tonight!" said Krystal which makes Tae Oh giggle. 

After 30 minutes journey and she arrives at The Grand Hotel. She parks her car at the groundfloor. She can see her sister was standing at the enter door. Krystal put her hoodie and wear a mask to cover her face. She carries Tae Oh and pass it to Mrs. Lee. 

"Kai wants you to be at the dress up room." said Mrs.Lee. 

"Where?!" 

"3rd floor, room number 206." 

"Nae.. arasso.." said Krystal and slowly make a step alone. She needs to use the front lobby. She makes herself relax and pretend like she is nobody. When she walks at the lobby, there's a lot of paparazzis and few veterans are entering the red carpet zone. At first Krystal feels so excited to see her favourite singer but she has something to be done. She quickly run to the lift and get to the 3rd floor. 

"Annyeong..." Krystal gives a bow after she enters EXO's room. 

"Wahhhh!! You've arrived!" shouts Beakhyun. Krystal open up her hoodie and mask. Her face was sweating. Kai gives her a box of tissue. 

"How is it?" ask Kai. 

"Extreme!! The paparazzi was all over the lobby. Damn scary!" nags Krystal. Others are laughing at her. 

"Where's Tae Oh?" asks Kai. 

"With my sister. So, when will you perform?" asks Krystal. 

"Just in a minute! If you wanna watch us, we will appear on the TV." said Suho. Krystal nods and smile. 

Just a moment, Krystal left alone in the room. She lays on the bed while watching TV. She can see Tae Oh who sits with his father and EXO. The fans are hilarious. The award begin with performance from SnSd. Nine beautiful girls with long legs and talented. She feels envy with the girls. The knock on the door make she stunt. It was her sister. 

"Kai asks me to accompany you. He sais you gonna be bored inside here." said Mrs. Lee. 

"Quite some." 

"Krystal... I notice something is weird with Kai." said Mrs. Lee. 

"Why? He looks in love again..?" asks Krystal while focus on the TV. 

"It's not something like that but it quite related. Well, I can see that he is so concern about you sometimes." said Mrs. Lee again. Krystal look at her sister with weird face. 

"I'm not joking, Krys...." 

"Well that it just your delutions. He is fine. Everybody will concern towards their friends right?" 

"I knew that... but Kai is quite more than that!" 

"Noona, please. We are just a boss-worker relationship." exclaim Krystal. 

"But, Kai said to me that you and him are now bestfriend." 

"Yes we are bestfriend." 

"Is there any chance for both of you to be more than that?" asks Mrs. Lee. Krystal remain silent. She feels her throut aching. 

"Tell me, since you had work with him for almost 4 months, don't you ever have feelings towards him?" asks Mrs. Lee. 

"No...." Krystal reply with a slow tone. 

"I don't think so. You are working with him, Krystal. Inside his house! Only you the outsider that can enter his house. Me as his manager also can't. How come you are not falling for him?" Mrs.Lee try to trap Krystal. 

"Noona, the past has teach him to not loving people when he had more commitment. And for me, the past has teach me that I must choose the right person. So, there's no change for us to be together. Its hurt when you get the punishment." said Krystal. Mrs.Lee nods. 

"Stop it noona.. I don't wanna talk about this. What you have to know is, me and Kai are just friends and business commitment." said Krystal and focus back on the TV.

Now, EXO needs to be ready for their performance. It is the closing performance for the award. Krysta who was in the bedroom is worry about Tae Oh. It is almost midnight and it already pass Tae Oh bedtime. She is pretty sure that Tae Oh will be in badmood after this. 

"Krystal, Kai text me to make sure you are down there too." said Mrs. Lee. 

"What?!!! He is not coming upstairs later?" ask Krystal in shock. 

"I think so. Let's go before EXO start performing." 

"Noonaa.... i'm scared!" 

"Just follow me!! Wear my tag and your mask!" said Mrs.Lee. Krystal had no choice and she just follow what ever her sister said. 

Kai gets ready to perform. The crew asks them to be at the backstage. Kai carry Tae Oh along with him. And when he stop at the path, he saw Mrs.Lee and Krystal not so far from him.
