Yuri katsuki is missing ? (Yuri on ice fanfiction)

Yuri's disappearance

Yuri katsuki pov:

I was stretching while listening to music to prepare for the world ice skating competition. Viktor walked towards me and smiled. He said:" Yuri if you win first place, I will kiss the gold medal that you have won. " After he said that, he winked at me. I blushed a little.

When it was finally my turn, I went to the rink and started skating to the music. When my turn ended, there was a loud applaud and cheers from the crowd. I smiled happily as I left the rink and I hugged Viktor. At the end of the round where the position was announced, I got third place. Viktor frowned and said:" Didn't I tell you to get gold.. " I said:" Sorry but I promise that I will continue skating until I finally win a gold medal. " When Viktor heard what I said, he smiled and nodded.

As we left the building, Viktor and I discussed about where we should go for dinner.

As we walked to the restaurant, a group of man in black suits appeared. They did just snapped their fingers and somehow it  made Viktor unconscious. After that, they just grabbed me and put me in a suspicious vehicle. I yelled :"LET ME GO!  WHAT DID YOU DO TO VIKTOR! I SAID LET ME GO! " One of the guys in black said:" Don't worry, I just erased everyone's memories of you and the man who is with you is alive however we just use sleep magic on everyone and that is why everyone in this world is unconscious except for us special bloods. All you have to do is obey us and he won't get hurt." I nodded and obeyed. At the same time, I wondered what do they meant by special blood...

Viktor pov:

What just happened?  Why am I on the floor? I looked around and wondered why do I feel like I had forgotten something important to me..As I wandered around, a man with black hair and silver eyes approached me. 

He said:" Please save my brother from them.... You are the only one who can.." I asked:" How am I to save your brother? " He just replied :" You already know. " After he said that, he disappeared. I thought what just happened? I'm confused.. What does he mean by the fact that I already know? 

As I was lost in thought, out of the ordinary a brick hit my head. Then I remembered that I fell unconscious and that Yuri was with me. I thought Where is Yuri?
