I started my car as she sits at the back seat. 

"Yah! Kim Go-eun! Why are you sitting there?? Are you planning to make me your driver?" She just looks at me and then she go back to her reading. Tsk. This girl is really! I started to drive when someone called me. I answer my phone by bluetooth so I can still drive safely.

"Why?" I asked arrogantly. 

"Yah! Why are you in a bad mood? Where are you?" I recognize this voice.

"Yah! Donghoon ah! Are you shouting at me??" 

"Ah sorry.. hehe. I'm just kidding around. By the way where are you? Can you fetch me? Hehe." 

"What did you say?? Why would I do that?"

"Eyy. My car is still on the repair shop. Pease." 

"Tsk. Arraseo. I'm near your house anyway. Ppali ok?!"

"Ok.. Thank You!! :))" Aish. This guy. If I know, he knows that I'm with my sister today that's why he wants to join. 

I stopped at the front of his house. 

"Are we at school?" Oh. I forgot she's here. Hm. Payback time!

"Isn't it too obvious??" Hahaha! Victory!! She looks at me again with her serious face.

"What did you say.. kookie?" Aish! I will never win from her. Tsk. Hmm. Why is Haha/Donghoon taking so long? I looked outside . And I saw a girl standing. Maybe waiting for a cab. And by the look of her uniform, I say were from the same school. Hm. What is she thinking that makes her face blank? I laugh at her when she hits her head. 

(He didnt know that her sister is looking at him. Thinking if her brother is crazy.) That girl is crazy! Haha! Then she whistles as she called the cab and take off. At the same time
