The door opened, the twins went straight to their bedroom. Loud thud heard, the door is closed. They had some arguments inside their room.

"What happened with you? Why did you come to me?" Sejeong said, little angry

Chungha couldn't believe what she heard "Why? Do you really ask me why?" Her voice had risen without she noticing "Sejeongah, they are not good for you, they will hurt you and I will never let that happen"

"No, they are my friends and now they will hate me because of you"

"Believe me. Look, you hurt your hands, they did that to you" Chungha pointed to Sejeong's hand

"I just fell by myself, they just made some joke before. I was too weak that time so I fell easly" Sejeong said defending her friends "So don't worry about me"

"How can? I'm your sister, your twin sister. I care, I must protect you" Chungha said, worried

"Stop it then, you'll only make it worse" she sighed "You made me lose my friends, I don't need twins like you" Sejeong said in a low tone but Chungha could still hear her clearly.

"Ya Kim Sejeong! Why are you being like this?" She said loudly

"Stop it Chungha! I don't want to fight with you. I'm not in a good mood to talk about this now, let's talk it later" she walked out of their room with a jacket on her hand

"Where are you going? I haven't finished talking to you. Ya! Sejeong! KIM SEJEONG!" The door shouted loud, it can be heard over the house.

Doyeon who walked in the kitchen for a glass of water, saw sejeong going out from the house. She heard the twins have some arguments but had no idea what was that about. Taeyeon who was sleeping woke up because that sound. 

"What's going on here?" She spoke and walked only to see Doyeon drinking her water

"The twins have some fight, maybe" Doyeon shrugged her shoulder

"Oh" Taeyeon responded calmly

"Unnie, how can you're so calm about this? This is a big fight" Doyeon asked, she was about going to Chungha's room

"Where are you going?"

"Unnie's room" Doyeon pointed to the twins room

"Don't. Let her be alone for now"

"But unnie--"

"Don't worry they're already grown up. They can slove their problems. You better go to sleep Doyeon"

"Yes unnie. Good night" she walked to her room with heavy steps, she really want to see her sister but she know Chungha maybe need her time, alone.

"Good night" Taeyeon went back to her room

Chungha was crying on her bed. She still can't believe Sejeong said those words, it hurts her but she can't hate her. *I don't need a twin like you* how can you said that Sejeong, she talked in her mind.

"Aaackkk..." her elbow hurts. She didn't feel anything before but it hurt now

"It's funny. I hurt myself like this, but I more worried of her than myself. Hufft....it's ok this pain is worth it because I can save her from a bad thing"
-

Sejeong sat on a swing at the nearby park. "Aaackk... Aww.." she felt her hands hurt. She had some bruises and a little scar, while Chungha's elbow is scratched and bleeding. She was thinking about what happened to her today.

*****

"Sejeong bring it to me in 5 minutes" said one of her friends

"Why me?" She asked calmly

"Because you're my friend, I think you are faster than us so prove it"

"I don't think so"

"Just ran and bring it now" her friend shouted

"But, I-" she couldn't finish her words, her friend pushed her until she fell on her .

Actually Sejeong just wanted to get more friends, but this time she didn't meet a good group of friends. Sejeong is a positive person, so she considers it as a friendly joke. But not with Chungha, she saw everything, she knew it wasn't right. She came closer and shouted

"Hey what did you do to her?" She run and help Sejeong, she bumped her shoulder to one of them accidentally because she was in a hurry to help her sister.

That person didn't like it and pushed Chungha to the corner. She fell, her hands hurt but she ignored it.

"Who is she?" Asked a girl

"My sister" said Sejeong

"Oh your sister? Tell her to be careful next time she meet us or she will hurt herself or maybe hurt you too" said the leader

"Who are you? Don't you dare talk to her like that!" Chungha was angry, looking at them then Sejeong "or I will tell this to the professor" added her

"Oh Sejeong, sorry I think your sister is not fun. We'll get our meal by ourselves then" They went and left Sejeong with her sister

"Are you ok?" Chungha asked, worried so much

"Don't touch me. I'm ok" she told her and left Chungha. Chungha is confused by Sejeong's act but she still following her until they arrived at home and fight.

When she was remembering about it, she saw her friend at the corner of the park with a younger girl. "What are they doing here?"

"Hey, give me your money or I'll put your bag to the trash bin" said a girl with loud
