(Y/N)'s POV
I appeared back at Ganon's castle, as usual, my brother was cleaning the blood from his sword. He looked up when he heard my footsteps.
-Hey lil sis! How are ya doing?
-I'm alright...I guess...
He gave me a questioning look and raised an eyebrow. To be honest, I didn't know why I felt so bad. You know those times when there is a heavy hurtful and weird feeling in your chest that makes you breathe heavily and dizzy? Yeah, that is how I feel right now.
I walked out of the main room and went to my room. I closed the door behind me and dropped on to the bed. I buried my face on the pillow and tried my heart to stop pounding so fast. 
My only thought at that time was
Link
Why the heck am I thinking so much about that stupid green bean?! He is my enemy! The worst thing in the world! But...
Why did I heal him before? Why couldn't I left him to die?
The worst thing...is that I betrayed my brother...I don't know if he could ever forgive me...
And...
Oh my Hylia...
FOR THE LOVE OF NAYRU!!
I-If Lord Ganon finds out...I don't even want to think what he could possibly...
With those painful thoughts in my head I suddenly teared up.
-FUCK!!! WHY CAN'T I EVER DO ANYTHING RIGHT?!- I threw the pillow against the door with a huge bump.
I started crying really hard and I just...couldn't stop...
I covered my face trying to keep the tears, hold my sadness...
I'm a dark creature...why should I cry?
I wiped my eyes after some time, when I was still sad, but the tears wouldn't come out anymore.
I hope no one never EVER knows, cause if they find out...I'm effed...
First, the dark kingdom would probably exile me.
Second, Ganon would probably kill me afterwards.
Third, my big brother...he would hate me and be disgusted of me...
I looked around trying to keep my thoughts in its place. I stood up and walked to the mirror, my (h/c) hair was a bit messy and my big (e/c) eyes were all shiny and red from all the tears I threw away. I still don't know why I look like a light creature, big brother doesn't look like it, he has black hair with pale greyish skin and bright red crimson eyes. Why do I look like this?
Oh well...I guess its just bad luck...at least I have fangs...
Whatever...

Dark Links POV
Why is (Y/N) acting like this? She is usually excited and comes running to me and asks me how my killing spree went...
I know when she is not okay, I just have to look at her eyes and, when she is sad, I don't see her usual sparkle on her big (e/c) eyes. That is what happened this time...I don't know what could have happened to her, but I need to find out. I promised mom and dad that I would take care of my little sister, no matter what it takes.

Links POV
After getting healed up by that unknown girl, I rode back home. I couldn't stop thinking why did she help me and who was her. Was she watching Dark and I fight all along? Then, why didn't she help me before? Maybe cause someone was preventing her from doing it? I don't know...
But I need to find her and thank her for her kindness, maybe if I ask around someone might know her...oh yeah, she didn't even let me see her face or gave me her name... What should I do?
Maybe Zelda could help me, her magic comes in handy often.
