Momo's POV

Since the day Sana saw Tzuyu, the two of us become awkward with each other. I still felt guilty for not telling her about it because I know it will turn out to be like this. She will be quiet all of the time and the cheerful one will be gone. Since today is saturday both of us just stay at home and do not have any planning to go out. I'm very sure if I ask her to go out right now she will definitely say no but still I want to ask her because I don't want Sana pay too much attention for her feeling otherwise she will be sick.

"Sana, let's go somewhere. I feel bored right now"

"I don't feel like going out right now, you just go with the other. I want to stay at home" she say with her fake smile on her face. I knew it, she will say no.

"It's not we are going somewhere like mall it just to Mina's house. Let's hang out with them because after this we might not be able to meet them often since all of us will be very busy" I tried to persuade her with my aegyo because I know she will fall for it and it's true all of us will be very busy until the day of charity program so I want to spend time together with them

"Don't give me that face Momo because you know I can't stand with it. Just promise with me only to Mina's house okay?" she pinch my cheek with her sweet smile on her face

"I promise with you. I'll call them to let them know"

"Okay I will change my clothes then" I just nod my head. I feel very happy that at least she want to go to Mina's house.

When I'm done calling Mina, I see that Sana also done. I drive Sana's car since she is not in the mood to drive. On the way to Mina's house we stop somewhere to buy jokbal, my favorite food and pizza since Mina said they will buy the beverages. Her house is not too far from our house it just take around 10 minutes to reach there and as soon as we arrived, I see Mina, Jihyo and Nayeon Unnie just come back from convenience store.

"Mina! Jihyo! Nayeon unnie!" I call them and they are waving back to us.

"You guys just got back?" I ask

"Yeah and we didn't expect you will be here so soon" Nayeon unnie reply to my question

"Well you should know how she drive right" Sana say and they just laugh while looking at me. Mina's house located at level 25 and yes it's the last floor of this condominium. It's a little bit scary for me and Mina but I don't get it why she still live in this house when she's afraid of height. I never go near to windows or balcony whenever at her house it just scared me to death. When we enter her house we put the food infront of the tv and sit in a circle to enjoy the food while watching the tv and sometimes we talk, tease each other and laugh out loud. I can see our cheerful Sana is back. I hope when we spend time together like this, she can forget about Tzuyu for a while.

"Yah Momo why you doesn't want this two call you unnie? You are one year older than them by the way" Nayeon ask me curiously

"About that, I'm just not used to it and furthermore it sounds like too formal and make me look old enough"

"But I really want to call you unnie. Can I call you unnie today?" Jihyo grinned at me

"Don't you dare to call me that or I will knock your head hardly until you forget about yourself!!" I give her a warn but they just laugh. I don't want people call me unnie because it look like too formal. We spend our time together happily and we share a lot of story and for the first time Sana share to them about her past with Tzuyu but they don't know that the guy from Sana's past is Tzuyu. They become speechless with Sana's story and everyone become silent so sudden

"It's okay unnie you are not selfish, you do this for both of your future Don't worry we will always be by your side no matter what happen" Mina breaks the silence and hug Sana to comfort her

"That's right, when something is bothering you just tell us. We are your family here" Nayeon add up and without Sana realise, she is crying with their words.

Sana's POV 

Their words really touch my heart. I don't know what will happen to me if they are not around especially Momo. Since the first day I'm in Korea, Momo always be my back bone. She care for me and always care for me. Even when I don't know how to handle myself, she will help without complaining. I still remember when I tried to commit suicide, she stay with me at the hospital since my parents couldn't come over to Korea and never for once she left me. She keep telling me that everything will be fine and ask me not to cry but I know that secretly she cry.

Flashback

"Sana! Open your door! What are you doing in your room?! You never lock your door before!" I can heard a fear in Momo's voice and she knock my room's door hardly until my door almost broke down

"Just leave me alone Momo! I can't do this anymore! I can't go on with my life it just so hurt. It hurt so much!" I cry badly as I don't know how to ease the pain that my heart felt that time.

"I know that you hurt Sana yah, but please open the door first. I will help you go through all of this pain that you have. I have promise with your family to take a good care of you and for me you are my sister. Don't do something stupid, please Sana"  I can heard Momo is crying too outside from my room but my heart won't listen to her words. That moment I saw a knife on my table and I feel like something possessed my mind, persuade me to take it and slashing my right wrist with it.

"Arghhhhh!!!!" I scream until I can feel my throat is hurt

"Sana!!! Open this damn door please or I will break it!! Sana!!!" I have no strength to say anything right now. I can feel my tears burst out from my eyes down to cheeks. All I can hear that time Momo is trying to break my door

"NO SANA!! ARE YOU OUT OF YOUR MIND?! WHAT WERE YOU THINKING?!" she yelled at me. She sit besides me and try to stop the bleeding while crying so hard. She called an ambulance and her hand is full covered with blood right now.

"SANA YOU HAVE TO STAY AWAKE, DON'T CLOSE YOUR EYES! LOOK AT ME! THEY WILL ARRIVE SOON JUST DON'T LEAVE ME SANA! I PROMISE YOU I WILL DO THE SAME! YOU ARE MY SISTER FOR FOREVER SANA!"

"Don't .... worry Momo.... whatever happen.... you have....... done your best..... to take.... care of me"  I said to her with a trembling voice as I put my hand on her cheek
