Guys this chapter is based on my own life but I have changed it a little.

Jungkook: Yeah ynaah!!run fast or else we will get late, please .

YN: aishh!! Wait na!! I am not Usain Bolt nor Jeon jungkook who can run fast.

YN's outfit:

Jungkook: ok slow down we can walk.

YN: hmmm.

Jungkook: Btw yn why sana didn't came yesterday?

YN: chaeyong knows it. 

Jungkook: What!!! You, her best friend, her secret partner don't know why she didn't came yesterday!!(Dramatically)

YN: (irritated) kook stop it!! I just don't want to talk about it.

Jungkook: okay bestie.

He sidehugs her. After sometime they reached the university. After they went yn saw sana and went towards her.

YN: hi sana!

Sana hugs her.

Sana: Aww!! Did my yniie missed me?

Yn nods her head.

Sana: you will sit with me today,okay?

Yn looks at jungkook. Jungkook nods his head smiling.

Yn and sana are seating together. The bell rings. The friend group was going out when isuel approached yn. She is a great friend of yn. She is popular in University. Yn and isuel are friends from nursery.

Isuel: hey ynnah!!

Yn: hey isuel.

She hugs her. Here sana rolls her eyes. Jungkook notices it.

Isuel: Yn I have given your and my name for english conversation competition,as teacher asked me. There are 3 first year students with us.

YN: ahhh!! Thank you so much isuel-shi. We will have a lot of fun there.

Sana: YN are you going to talk or eat lunch? Talk as much as you want.I am going if you want to come then come.( Says annoyingly)

She goes from there angrily. YN's smile dropped after hearing to sana. Jungkook notices it,as she had classes with jungkook and sana.

YN: sorry isuel. Don't mind her . She is just not in a good mood.

Isuel: it's okay ynnah.

YN: let's go jungkook.

Jungkook: hmm bye isuel and sorry for her behaviour.

Isuel: it's ok jungkookshi.

They both went from there. After yn went to towards their friends group she didn't saw sana. She looked around the cafeteria and spotted her on a seat eating alone.

YN: guys I will come in a minute.

Jimin: but yn your lunch--

Taehyung: yn come here and eat it.

YN: oppa please 5 minutes I will come in a flash of light.

Yn went towards the seat where sana was sitting.

YN: hey sana why you sat here alone?

Sana: I don't want to eat with them. If you want to go then go but I am not coming.

YN: but what happened? Atleast tell me.

Sana: it's nothing just go and sit with them.

Yn the whole time was going from one table to second table. Jungkook was worried for yn but he didn't said anything.

The next class began. Sana and yn were seating together again. The teacher was absent that's why they decided to make notes of bio.

YN was talking with some boys which were her friends and studying at the same time.

Sana:(in mind) how can she leave her bestie? She is even talking with boys.hmm. The girl who didn't even used to talk with boys is now laughing and chatting with them. I introduced every boy to her and now look at her. She is enjoying without me.

Sana: YN.

YN:yes.

Sana: I will never sit with you again.

YN: ( shocked) what happened sana? Why are you saying this? Did I do something wrong? Please tell me.

Sana: You don't study when you are sitting with me. Just do it. And never talk with me,we will break this friendship here.

YN tries to convince her a lot but she didn't listened to her.

Yn was crying after she went home. She writed a letter to sana of being sorry and she also cutted her hands with Razer.

Second day she wore full sleeves so that no one would notice it. She gave sana the Letter. And they became normal again.

This days sana used to leave yn alone to talk with her friends. But when yn did the same she was getting very angry. Whenever isuel talked with her,she would not talk with yn. Yn used to sorry everytime even if it was not her fault. Isuel tried to talk with sana even if she behaved rudely with her. One day sana told isuel to stay away from yn and isuel cried a lot. But still she tried to talk with sana. But sana never behaved nicely with isuel. Sana used to taunt yn about isuel . Like go and stay with isuel who I am even to you now? And yn used to convince her daily.

Yn was a bright student of her university. So every teacher take her in every competition. When one day there was a competition, teacher called yn and told her about xxx competition. Sana cried very much why didn't the teacher take her? She said these are the people who do everything for uni. We are no one. Whenever something good happens it is yn. Why? 

Yn was so hurt that time but still she consoled her.

Sana's behaviour was not normal with yn. She didn't talked much with yn. She used to taunt her but yn still used to take it jokingly even if she was hurt. Everything has a limit. And the limit of YN's patience broke one day. She stopped talking with sana. There was a function in the uni. And everyone was just chilling because there was no teacher. Yn and her other friends were talking with isuel.

From the other side sana and her other 2-3 friends started singing songs like,              bedardeya,jhoota pyaar,bewafa tera masoom chehra, etc.( if you don't know these songs then see it or their subtitles). YN knew that the songs were a taunt for her but she didn't reacted.

Yn was a person who cares about relations a lot. She never breaks a relation very easily. But everything has a limit.

It was a day where yn was waiting for dahyun in the corridor and suddenly sana and her friends came there. She tried to ignore them but sana held her hand and said do you want to talk? That too very arrogantly.( Guys I want to tell you whenever there was a quarrel between us I was the one who used to say sorry but she didn't even said it she just used to message about how I broke the promise of being together and she posts very bad things about me and my best friends on social media). Yn tried to snatch her hand but it was of no use.

Dahyun saw it and noticed yn was on the verge of losing herself. She immediately called jungkook who was in the garden.

Jungkook came running there. He snatched YN's hand from sana and went towards rooftop. Dahyun know yn needed time so she didn't went there.

As soon as they reached the rooftop yn broke down into tears. Jungkook hugged her immediately.

YN: why koo?why? I always tried to keep our friendship. What is wrong with me? What is my fault that I always wanted to have friends is it? Why everytime I give my everything to a person they just break my heart. Why? Do I not deserve her? Was I not a good friend? Why,why,why?( She said while crying)

Jungkook listened to her everything.after she calmed down a little he said

Jungkook: yn tell me did she ever said sorry when you both fighted? Which friends get jealous on their besties success huh? I always know when sana used to go to Irene to talk with her how alone you felt. But you never said anything. But she can't do the same. You love when she interacts with new people, but did she ever had that filling? YN this is not how life works. We have to interact with new people, we should make more than 1 friend. It's over now ynaaah . Don't try to fix the broken glass. It can't be fixed , it will only hurt you. You have me, jimin,dahyun, your family even isuel too. Please get over her. Not every friendship needs to last for lifetime. I've noticed your sadness, your tears everytime because of sana. But never said anything. Not now yn. I am here and I will never leave you. People always say the one who brokes the friendship first is the wrong one but it is not true. Where was sana when you cutted your hand? Where was she when you needed her? Where was she when you felt alone? Ynaah forget her please 

YN: jungkook I don't have any feelings for her now. Sometimes you need to break some relations to keep your worth. I am always thankful to all of you. Thank you for being my bestfriend.

So guys this is the end. I know what my ex bestie did with me was wrong. But she is a stranger to me now. My friends whom I hurt at some point were the one who supported me. Comforted me. Even isuel her real name is different she is very sweet. She even lost her best friend because of sana. I just want to say even if your friend is making new friends it doesn't mean that he or she is living you behind. Just trust them before they break completely. I have went through it and it hurts when your own best friend don't trust you. But she always blamed me for everything and never once said sorry. I think sometimes letting go is better option than holding on. I am and will always be thankful to best friends of mine who supported me in that time. Even if it was not their fault sana talked very bad about them. I used to think that isuel was not a good girl because sana used to think that but when I spent time with her I know she was a very sweet girl. So please never judge a book by it's cover. Even if she hurted me I am not able to forget her, I am trying but it's not easy. I wish she just disappears from my mind completely Thank you and sorry for troubling you 🙂🫂

And one more thing please trust your friend please 🥺
