Krystal's POV       "What are you doing Yoona unnie?" I asked my sister's best friend who is looking in the folder that my sister just gave her.   "Uhhh.. It's just the information that i needed in my project, your sister helps me browsed because I don't know some of the words in English." Ah so that's why the folder looks familiar because its the same thing what she's looking at yesterday while frowning.   " Okay , my sister just told me yesterday that you have a crush is that true unnie?" I told looking at her with full of confusion. When I asked her that her calm face became surprise who will not be surprise when you're best friend just tell you're secret to her sister right?   "Aniyoo!!!!. I don't have a crush!! It's just that she's cute while frowning. She's not my crush I don't  even know her what year she is or whatever it is to describe someone." She's talking rapidly while explaining I think she has a crush on that girl because she looked so shocked and embarrassed. Check she really has a crush she's blushing! The Im Yoona is blushing    I laughed like a retard person because her face is reallllllyyyy funny!   "Yah Jung Soojung why are you laughing?? huh? are you laughing at me?" She ask, she's serious she never call me with my full name if she's not serious *gulp*   "Mianhae unnie it's just that your face is really funny" I smile at her while making my face that I am really sorry.   "KRYSTAL!

When I look at my back there she is my sister looks like a bull with the face in the anime that there's an air coming out in the nose and ears ?? yeah that, that is the face of my sister right now/   "uhh Yoona unnie do we need to run because it's hellsica" I said my voice shivering im sure also Yoona unnie is shivering I look at my side and when I saw Yoona unnie i am right she's shivering and to add she's sweating like hell.   "Yah you two why are you here? Do you remember that I said that we will meet at the canteen right??" My sister ask pinching our ear while dragging us towards canteen. OUCH!   I dont remember unnie saying that to us.   "  AWW AWW Yah!

Yeah I am about to cry because my bruise in my right ear is not fully healed    "Unnie maybe your'e talking to an air because, don't you remember me and Krystal is listening to music with earphones and it is in our both ears remember????" Yoona unnie explain while rubbing her left ear I let Yoona unnie explain because I am holding in my tears I dont want to cry infront of the student who are looking at us.   "Uhh yeah Im sorry it's just that I have a bad morning that midget in my classroom is teasing me." she said while frowning.   "It's okay Jessica unnie we understand right Krystal?"
