They were together at first but separated at second.

Someone's POV:

I was sleeping in a dark yet comfortable place, the place that used to be so big for us but now too small for us.

We were bumping to each other, I surprisingly kick her and she kick back.

“Ahhh~!” We suddenly heard a screaming voice, her voice... the angel who brought us here, she was screaming in pain, we wonder why; is it because of us? But we love her.

I can sense that she was worried for out angel, she kept kicking; wanting to get out

My hand brush against her head, she stared at me. I blinked my small eyes at her, she smiled at me and brush her hands against me, her eyes are telling me 'it's gonna be okay, I'm here', I smiled knowing that I was safe.

The place where we're lying was getting smaller, it was sophisticating us; we wanted to breath, when suddenly she was being pushed out.

I held her hand but she looked at me 'Let go' her eyes were saying, I nodded and let her go, but her head was caught up by a long rope, “Stop!” I shouted but they didn't seem to hear me.

They kept pushing her out, she was dying, “Leave her alone!” I shouted in tears but they didn't heard me.

She was holding tightly on the rope, trying to get out but the rope was too strong, “Stop it!” I shouted but they didn't heard.

I wanted to pull her and save her but I can't move; I cried, shouted and screamed but they kept killing her, our angel didn't even save her.

Suddenly her tiny hands let go of the rope and her eyes close,and she was pulled out, I blinked, where did she go?

I kept dangling my hand in the space but I couldn't seem to touch her, where is she?

Huh?! I'm suddenly being pulled out!

I'm not ready to get out yet! Someone help me.

“Push! Push! Push!” A heard a loud voice said, I was being push out, what are they going to do with me?

I suddenly saw a bright light, I cried; The place we used to lie, where is it? But most importantly is where is she?

“She's beautiful” The man said as he took me in his hands, “I'm sorry about the other one, her umbilical cord was tied in her neck... I'm sorry Mrs. Im we tried our best” The man said in a pitiful voice.

“My Yuri” I heard a small cracking voice; a voice, a very familiar voice, could it be? Our angel!

“I'm sorry, Mrs. Im” The man said “But you still have another healthy beautiful baby” he continued and suddenly gave me to someone.

Her arms were warm, very warm, “I'm sorry, you lost you're unnie” She said in a crying tone, she suddenly kissed my forehead, “Don't worry, mommy is still here, Yoona, My Yoona” She said.
