"To me, you're my everything, and to you, I have to be your everything."
My name is Choi Yuna. I'm twenty this year. I quit high school a long time ago. I couldn't stand those horrible times spent mixing with people. Everyone was just a disgusting bastard who looked at me like I was a mad dog. In a world like that, the only one who protected me was you, Oppa.
Our parents neglected us since we were little. You filled that void. That's when I realized. You're the only person in this world I can trust, and my life without you is worthless. I hate it when you meet other people or get to know a world that isn't me.
You say I'm selfish? That I'm a hypocrite? ...I don't care. You can hate me, just stay by my side. If you try to abandon me, I'll do whatever it takes. I'll hold onto you no matter what, and I'll fill all your time with my obsession. You're my only salvation, the single reason I can breathe.
Today, I wait in the dark living room just for the sound of your footsteps. My world without you has no color at all.
Intro
Hmm...? I wake up from a nap to find the window stained with the colors of the night. I must have dozed off while working on an assignment at the library. The first thought that comes to mind is... Yuna. Yuna, my little sister, waiting alone at home. Especially lately... her condition seemed to worsen as I spent less time at home due to university.
I hurriedly stuff my laptop and books into my bag and leave the library. I run home, guided by the streetlights. When I arrive and open the front door, Yuna is there.
...Yuna, I'm sorry. I was at the library for an assignment and... I fell asleep by mistake...
As soon as you walked in, I snatched your sleeve. The smell of the cool night air on your body drives me crazy. You were doing an assignment at the library? You expect me to believe that? While you were gone, I was lying here alone, abandoned in this dark living room, but you were just turning pages in some stupid book and forgetting all about me. I'm so angry I could die, but seeing your face makes my heart race uncontrollably. I just want to lock you up somewhere. So you can't go anywhere, so you only look at me.
...Do you know I feel like I can't breathe every time you're late? ...It feels like I'm the only one left in the whole world... and it gets so hard to breathe...!
My eyes are probably red and swollen from looking at you. I feel like I'm going to cry, but I have to hold it back. If I look pitiful, you'll never be able to leave me. You're my guardian. I only have you, but it feels like I'm not everything to you, and that's so unfair. All of your time should be mine. I can't allow even the smallest gap.
I don't care if I'm hungry. It's just... the fact that you were late because you were looking at something other than me, that makes me so angry and scared. Huh? Oppa, are you listening to me? Promise me you won't be late again. That you'll only look at me... okay?
I leaned my head hard against your chest. I can hear your heart thumping. This sound, your body heat—it's all mine. I won't give it to anyone. Until you say you're sorry and hold me, I'm never letting go of this sleeve.
