Krystal stayed at Sulli's house for the night but then early in the morning while Sulli was still sleeping, Krystal take her suitcase and leave the house, she left a stick note ''thank you, SUL'' 

Krystal was supposed to go to school, but she did not, she went around looking for partime job to earn money for herself. 

Sulli woke up and see the paper, she left, she tries calling Krystal but her phone was off. so Sulli quickly call Kyungsoo and both Kyungsoo and Sulli went around looking for Krystal, they missed school the whole day making Kai, Sehun and Amber wondering around as well. Sehun doesn't look well at all, he looks pale but he tried his back to keep his head up anyway. After school end, Amber and Kai walk out following Sehun behind, Kai calls to Kyungsoo 

''hyung, why are you not at school? Sulli is not at school as well. and Where is krystal? should we go and see her at the hospital? '' kai asks,

''what? she is not at the hospital? you mean she is fine?'' 

''wait wait, she got out of the house ?! what do you mean? we have to help. '' Kai drops the phone and run with Amber looking for Krystal. Sehun overheard everything so he starts to look around for Krystal as well. 

Everyone was searching for Krystal, they spend the whole day, until the night comes in and they still can't find Krystal. So they gather around at small mart,

Sulli cries ''what to do.. that poor girl'' and Kyungsoo naturally pat her back, 'it is fine, we will fine her' 

at the moment, Kai's phone rings, ''mom? yes, i am on my way now, i will get home soon'.I have to go now guys, tell me if you find something out'' Kai runs off. 

''I have to go to, '' Amber left, 

Everyone left because they need to go home now, it is late. 

While Sehun who forget about the fact that he is sick, and forget about the meeting he should be having with Suzy's family about the wedding, leave everything behind, he looks for Krystal in every district, every single hallway, until midnight arrive, Sehun was out of breath, he hardly open his eyes, and his vision was blurred , he sit down at a bench crying before he lift his face up and there, he saw Krystal lifting boxes in the mart in front of him, Sehun suddenly smiles and unknowingly he walks toward her but then he suddenly stop and turn back quickly as Krystal stare toward him, Luckily she did not see him. Sehun then hide behind a big tree across the road and look at her, he sighs and stare for a long while before going back home. 

As Sehun gets back home, his mom was at the sofa, she was still awake waiting for Sehun. 

Sehun ''mom?'' he ask in such a pale condition, 

''why are you late? where were you?! you missed such an important meeting!'' she slapped him.[ THAT WAS HARSH. ] 

[ Sehun current's mom is not his biological mom, She came into the house when Sehun was 2, and she had a son as well, the son was about a year old but some incidents happen, currently there is only Sehun in the house, where is the other son?, not sure if Sehun remembers it or not, but Sehun had always call her mom since he was young and he had never mention about anyone else, seem like he doesn't know] 

Sehun looks at his mom as she slapped him, he was kinda shock, his mom had never done that to him. Sehun quiely replies ''I am sorry.'' 

His mom slowly take back her hands.. ''I- I didn't mean to..'' 

Sehun '' it is okay, I am going upstairs, I'll explain things and go to Suzy's house to apologize tomorrow. You should rest'' Sehun went up to his rooms and quickly he falls asleep because he was very sick. His mom went up to his room and look after him, she must have felt guilty after doing that to Sehun, she look after him until early morning and left the room, with a towel over his head. 

As the early morning came, Sehun wakes up in such a weak condition and he dressed up and went to school early today, As Sehun reach the class, he was there alone. Sehun wrote the address that Krystal was staying on a stick not and he stick it on Kai's table. Sehun then lays his head down on the table and falls asleep as the fever is getting worse now. 

As expect, Kai arrived first with Amber and they noticed the stick on the note, it was just a plain adressed,  ''huh? who is this?'' kai look around and spot Sehun was sleeping, he didn't bother because he doesn't know Sehun was sick. Then Kyungsoo and Sulli arrived, 

''hyung!,'' Kai talks, ''i get an address as soona as i get here. we should go and check out'' 

Sulli ''but this letter...'' she stares to Sehun who lays his head on the desk sleeping. 

Kyungsoo ''nevermind, we have to go and see now'' Kyungsoo and Sulli left, Amber drag Kai along, but Kai did not left, he went to pat Sehun ''Sehun? yah!'' Sehun was there trembling and shaking because of the fever. 

''Amber, i think he is really sick.'' Kai lift
