"Tae Oh still sleeping?" ask Kai and pass a coffee to Sehun. 

"He had a nightmare last night, hyung." said Sehun. 

"Me too..." 

"Hyung, what ever your feeling is, you have to keep on calm and strong. You must be more then just a father after this. For Tae Oh that is very important. So, you need to be very generous and able to fight for this obstacle. I know there will be a rainbow after the downpour. I believe that, hyung. If you love Tae Oh, so you can do this, hyung." said Sehun. Kai look at him and sigh. 

"I don't know how to explain this to Tae Oh! He really close to Seo Ni. All of his time was with his mother before this. He will search for her mother! I just.... I don't know how to tell that, to tell that his mother was no more in this world!" express Kai. 

"You can do this, hyung. Tae Oh can understand you. I know." said Sehun.

"Awesome, hyung! but too much exhausting!" said Chanyeol. Kai rest his back on the mirror while listening well to what his manager is talking. 

"Kai? How about you? are you alright?" ask Mr. Park. 

"I do. But, can I just bring Tae Oh here? I'm scared what is he doing without me in the hotel." said Kai. Others are silent. 

"There's too much fans over here. Yet, you still have the ending performance. I dont think you can handle it. Our script writer was there with him." said Mr. Park. 

"He is my son. Let me handle this. Give me 20 minutes, I'll be back!" said Kai and left the studio and the hall. With full of covers, he run away from the hall to the hotel since it was just around the corner. He quickly approach his room.

"Appa!!!!" Tae Oh run happily to him. Kai give him a kiss on his chubby cheeks. 

"What are you doing outside? You suppose to be inside the room with ahjumma!" Kai nag. Tae Oh pouts a little bit and show him one lady who was standing near the window. 

"Who is that?! You play outside with stranger Tae Oh?!" Kai almost blows up. 

"Omo! Kai! You are back?" Mrs. Lee shocked when she saw Kai was carrying Tae Oh. 

"Noona...." 

"Anyeonghaseyo.." suddenly somebody interrupt the conversation. Kai startled a bit when suddenly Tae Oh open his arm and wants the girl in front of him to carry his son. 

"Mianheyo Kai. This is my dongsaeng who studies here. I ask her to come and help me take cares of Tae Oh. She really loves kid." explain Mrs. Lee. Kai stuck at the present of the lady in front of him. 

"My name is Krystal. Nice to meet you, Kai." said Krystal and give him a polite bow. Kai pause. 

"Appa! noona is my new friend!" said Tae Oh excitedly. 

"Noona, dont simply make your own decision. Either she is your sister or what ever she is, please let me know first. Tae Oh is a public figure boy. Since we are at people's country, I dont want anything to happen. I hope you understand. And you... thnks for this. But later dont do it anymore." said Kai and quickly carries Tae Oh in his arm then walk away back to the hall. 

Krystal can't hold her tear. Her heart crash to pieces after she saw her fiance with other girl. After what she had done, this what she get? Krystal enters her house and smash herself on the bed. This make her roomate worry about her.

"Yah, Krystal.... what happen? Why are you crying?" asks her roomate.

"I'm so hate of it!!!! He is such a big lier!!! I hate him!!" said Krystal while throwing all cushions and pillows on the floor. Amber hugs her tightly to make her calm. 

"I want leave Japan...." express Krystal. Amber quite shock. 

"You still have more classes in here! Krystal... don't be like this.. let him talk the truth first." 

"Truth? The truth, you say?? I saw it! In front of my eyes!  What the other truth you say?!!" shout Krystal. Amber silents. 

"But this is not the reason you need to leave Japan. There's the other ways." explain Amber. 

"No way! This is my decision. Plus, to study in here 2 years ago it's all my sister idea to keep me and him stay close. But, you see.. I stop! This time I really fed up with all those coming! Please Amber. Keep this as a secret. If he come and search for me, just inform him that I will never want him back in my life. And this..." 

Krystal takes out the ring at give it to Amber.  Amber startles. 

"Return it to him. Ask him to throw it away!" said Krstal and leave Amber alone in her room blankly. 

After she took almost 2 days thinking as much as she can and the final decision is to be back in Korea with her sister is more relevant than being fooling by her own damn fiance. The incident 3 days ago was not the first time she saw. It was more than 5 times she looked and watched all games given by his fience. And now, she is no more giving commitment for that guy. She is new now. And, she is back as a Korean lady. 

"Omo! Unnie!!!!!!" Krystal run towards his sister who is carry a kid wearing a mask. 

"Who is this kid? Is it Tae Oh again,unnie?" ask Krystal. Tae Oh than surprise Krystal by open his mask. 

"Noona!!! Annyeong!" 

"Aigooooo this boy! Come, let noona carry you." said Krystal. Tae Oh than put his mask back. 

"Unnie, is it Kai know you bring him along?" ask Krystal. 

"Nope. He was busy with his new song. He asks me to take care of Tae Oh for a while. So, since he didn't notice me take out his son. Haha!" 

Without saying any words more, both are shock by th caller from Mrs. Lee phone. Krystal quickly shut up. Tae Oh keep on silent.

"Yeobuse....." 

"Where did you bring my son, noona?!!" shout Kai. Mrs. Lee almost lost her rhyme of heart beats. 

"Errr... He is with me..." 

"Where?!" shout Kai. 

"Airport. I bring him along to fetch my sister arrive from Japan. We are on our way back, Kai." said Mrs. Lee. 

"Appa!!" Tae Oh suddenly call his father. Kai at the studio breath unconciously. 

"Son, palli came back here!" said Kai. 

The conversation end. Mrs. Lee drive clumsily. She can't breath properly. 

"Yah! noona! you suppose to get his  permission first! Aigooo... ! Drive save Noona!! There are two lives in this car!! Noonaaa!!" Krsytal shout because of Mrs.Lee driving. Tae Oh hug Krystal neck tightly. 

After 20 minutes, they all arrive and Kai was already waiting for them at the front door of the studio. Krystal bite her lower lips while walking slowly with Tae Oh. Mrs.Lee give him a apologize bow from far

"Appa!!" Shouts Tae Oh while running to Kai. Kai quickly carry him in his arm. 

"Kai, i'm so sorry. It's time for me to fetch Krsytal so, I just bring him out. It's because you are still recording just now so..." 

"This is not the first time, noona. I've already said that Tae Oh is public figures." explain Kai with disappointed tones. Tae Oh look at his appa. 

"Don't get angry,Appa..." Tae Oh tries to console his father. Kai breathing hard. 

"Kai, let me introduce back to you, this is my dongseang..." 

"Her name is Krystal. I still remember that. So, please don't change topic!" said Kai and makes Krystal amazed. He still remember her name after just look at her by glance two weeks ago. 

"Come in, let discuss about this." said Kai and they enters at the lobby of the studio. Tae Oh start to wandering around at the level. He starts to disturb and tease the cleaner and new freshie at the dancing room. Meanwhile,Kai still in serious mode with two ladies in front of him. 

"I'm so sorry about what had happen." said Mrs. Lee. 

"I really trust you because you already had two daughters. I know you really good in taking cares of my son. But, this you cannot simply bring him out like that, noona..." Kai explains more. Krystal just stay silent. She scares to open . Suddenly Tae Oh run and sits on her lap. 

"Noona!! I want to play games!" said Tae Oh while asking Krystal to unlock her phone. Kai looks at Tae Oh and look at Krystal. 

"I think I should replace your job, noona." said Kai to Mrs.Lee while he is still look at Krystal very deep. Krystal then turn up her head and both eyes meet. Both are freezing. Mrs. Lee could see something wrong somewhere with the situation. She hides her joys for a while and tease them by clear . Both back to a reality. Krsytal hide her red face with her hair and focus back to Tae Oh who is playing games. 

"I think your dongseang should replace you." said Kai. Krystal surprises with his word. 

"Are you sure,Kai? She just new and I bet she still don't know about the rules of being a babysitter for Tae Oh!" said Mrs. Lee. Kai smirks a bit. 

"My answer coming from the action she did. Since, Tae Oh is keep on talking about you after coming back from Japan two weeks ago, so I think you quite suitable for this." said Kai. Krystal looks at her sister. She looks blank. 

"Noona! I win! Appa!!! I win!!" Tae Oh shouts. 

"Jinjja?! Omo, my son is good at gaming." Kai praise his son and glare at Krystal a little bit. 

"Can you give me a time to think?!" ask Krystal after silent for a long minutes. 

"I want the answer tomorrow on 7 a.m. Sharp 7!" said Kai. Krystal scratchs her unitchy head. 

"errrrrr......nae....." she anwers him slowly. Kai hides his smile from them. But,  Mrs. Lee notice something weird with Kai recently. 

After giving answers and yes! Krystal agree to be a babysitter for Tae Oh. The jobs given was started after she agreed. Now, it is 8 in the morning. Kai welcoming her who already arrive. 

Krystal feel so much nervouse. She returns to Korea for good but suddenly she gots a big job from international singer. She sigh in nervous and she takes a step to Kai's apartment. She arrives and rings the bell. Kai open the door with a morning smile. Krsytal slips her hair behind her ear. 

"Annyeong." 

"So, welcome in.... you are very punctual and I like it." said Kai. Krystal shocked by the view of the house. Very neat and tidy. Even, Tae Oh's toys also keep neatly at the corner of the living room. 

"Tae Oh is still sleeping. Have you breakfast?" asks Kai while pours water on the glass. 

"I've done breakfast. It's okey." 

"So.... you don't have to be shy. It just you and Tae Oh to be here after this. But there' s a few rules more that I want you to listen." said Kai. Krystal ready to hear what him saying. 

"First, you have to make sure everytime you come, nobody notice you on this row especially in front of my house. Because, everybody knows i'm stay in here. Second, don't give Tae Oh any ramyeon as breakfast. Give hime milk. If he don't want, ask him what he wants but not ramyeon and presevations foods. Third, you can bring him out but only around this apartment. If he still boring, just bring him to my studio. You get me?!" 

"Nae, Kai...." 

"Okey, fourth, make sure he gets a nap around 12 a.m after lunch. Make sure he eats his lunch! Fifth, for lunch you must cook him something more green. Brokoli and salads are important. Sixth, if he keeps on crying and you couldn't control first you should do is try sing a song. If he still crying, read him a storybook or play with him. But if there's nothing change, just call me. That's all rules for you." said Kai. Krystal nods understand. 

"Err.... Kai..." 

"Yeah?!" 

"Can I know what really happen to your wife? I heard from my sister that she had an accident a few months ago. I'm so simpathy with you and Tae Oh." said Krystal full of sincere. Kai stuck a word. He don't want to recall that nightmare. 

"I think you've already know. So, I don't have to explain more. Thanks for the simpathy." 

"By the way, why suddenly you choose me to replace my sister?" asks Krystal more. Kai turns to look at her. He gives her a smile that make Krystal blush. 

"You will know the answer later. But if you treat Tae Oh very well and follow the rules." said Kai. Krystal nods.
