Special relationship

Promises

Dahyun POV
I could feel Sana breathing on my face but her lips weren't touching mine. Confused I opened my eyes and she was staring at me. Then all of a sudden she started to laugh.

"Aww did little Dahyunnie think I was actually going to kiss her? Puhahaha."

She was holding on to me while laughing in my face. I started to get irritated so I pushed her off of me and stared at her laughing. Finally after a couple of minutes she stopped laughing so I waited for her to catch her breath. When she was fully recovered she looked at my angry face and gulped. I started to walk forward and she started to walk backwards.

"Dahyun? Dahyun I didn't mean to joke around. Ok fine I-"

Before Sana could finish her sentence she hit the wall and had nowhere else to go. I put my both of my hands on the walls and trapped her. I moved my face close to her ear and she flinched while closing her eyes. 

"I swear Minatozaki Sana. If you ever do that again. I'm done being your best friend."

"Da-dahyun I wont do it again. I- I promise!"

I looked at her face and thought she looked a little cute because her eyes were still closed. I couldn't hold back so I kissed her on the cheek. I took my hands away from the wall and I started to walk to the door. Before I could open the door Sana started shouting at me.

"KIM DAHYUN! Come back here this instant! How can you tell me not to joke around but you can!"

I looked back at Sana and winked at her after blowing her a kiss. Her jaw dropped and she just stared at me.

"Sana were going to be late to class let's go and close your mouth. Also that kiss was to show you that your my only best friend. This will be our secret and if you aren't satisfied with cheek kisses then maybe we can spice it up a bit." I moved my eyebrows up and down while smiling.
Sana ran towards me with a red face and started to hit me with both of her arms.

"How can you say these things so casually. I hate you!" She huffed and walked off.

School is done
I started to walk to the front of the classroom to go home with Sana but she still looked a little pissed. Then right then I thought of an idea and said bye to my friends while running out of class.

"Bye Jeongyeon, Momo, Mina and Chaeyoung! See you guys tomorrow!"

Whoops I forgot to say Sana's name. I hope she isn't more pissed then before. Sorry Sana I ran out in a hurry because I was excited to make you not mad at me anymore.

Flashback (4th grade Saida)
Sana was sleeping over at my house and we were laying in my bed. Nobody was talking but all of a sudden Sana started to talk.

"Dahyun-Chan let's make a promise. If one of us is mad then we have to forgive each other when one of us buys Saida."

"Saida? Why Saida?"

"Because when you put our names together it's Saida! We are going to be best friends forever! Nothing can separate us but death or-"

"When the last bottle of Saida runs out! Saida is the best couple! I love you so much Sana-chan!"

"Cou-couple? Dahyun-chan that's embarrassing." Sana hides her face in her hands and I was worried I said the wrong thing.

"Sana! Sana! I didn't  mean to say couple. I can take it back. I-I'm Sorry." I turn around and tried not to cry but my tears started to fall because I thought I hurt Sana's feelings. I started to tremble because I couldn't stop crying. Right then I feel both of her arms wrap around my body.

"Can you look at me Dahyun?" I turn around and look at her but I'm scared she would have an angry face. Instead she's smiling at me and she holds me tightly close to her heart. She waits till I'm done crying and then starts to talk. "I'm not mad at my Dubu so please don't cry. I hate to see tears falling from your face. I was just caught off guard when you said couple so I tried hiding my blush from you. I love you too Dahyun and we'll be best friends forever ok. I also promise that I will never make tears fall from your eyes especially if I'm the one making them come out" Then she kissed me on the forehead and we went to sleep with smiles on our faces.
