Sakura's betrayal

Training

Sakura's pov
"SAKURA CHAN!!!!! Wake-OUCH!"
When I heard the screaming, I immediately punched the thing that was closest to me as a reflex and that thing happened to be tobi. "ERGH! Tobi what do you want?!?"
He replied," Itachi senpai is calling you and he's getting angry, sakura chan!" I replied with a simple 'oh' and went to wash up.
Once I was done I dashed out of my room to meet Itachi for my training. I was sooooo excited that I forgot to have breakfast but it's ok. Time for me to train, it's been too long!
---------------time skip------------------
"Itachi san, can we start again ?" He nodded, still panting from our training session. Itachi has been training me to break out of genjutsus as well as not showing any trace emotion during a fight. Suddenly my head started to throb. It was pounding then suddenly everything went black. "Sakura....sakura...it's time I show you who you really are. You aren't actually a haruno. Those parents are actually fake. They were hired to be your fake parents and your clan is- "
"Sakura!! Wake up!!"
Slowly I got up. I saw I was still in the training grounds of the akatsuki and Itachi was staring back at me. "What happened? You were resting then suddenly you screamed and blacked out... Are you ok sakura chan?" Itachi asked with very very slight worry in his eyes. I nodded got up and left. I had much to think about.
"Inner are you there?"
"Yes I am sakura chan..I think it's time for you to know the truth..I'm not your inner I'm actually the prince of death. Your mother, real mother sealed me in you when you were born and put a seal so that your true powers will not show, she made a deal with me to not tell you anything about this unless you decide to leave the village, which she thought would be very unlikely. She thought that she could keep you safe by making you weak so that's what she did. I know what you want. Your desire to crush konoha and I will help you because I want to help you sakura, my mistress and host. My time is up, we will speak again. Till the next time sakura, till then, stay safe."
I couldn't take in all the things that inn- I mean prince of death was telling me. First of all I'm not a haruno?!? I really have to speak to Itachi.. After all he's the only one I can trust as I've gotten closer to him over the past few days.
