I looked over at my cousins Jisoo, Jennie, Rose & Lisa and they knew by the look in my eyes that something happened Jackson, Mark, Yugyeom & Taehyung also picked up on the look and they knew. After school we all met and my brother and I showed them the message.
"I swear it's just been a couple days since we've returned and we already have someone following us" Minghao said and you could hear that he was furious. "Don't worry we know what we have to do" Lisa stated
"I don't think we've ever found someone who could take all of us down especially when your other cousins arrive" Jackson stated
"He's right and plus we have to train not only ourselves but our supernatural side" Mingyu stated
"I forgot that you guys are like us" Jisoo exclaimed
"You forgot!! Really!!" Jungkook said in disbelief
"Sorry" "It's ok" Jimin replied.
"We'll figure things out like always" Mark ensured us
"Let's head to headquarters" Jimin said
"Let's go"  we all said in unison

We went straight to headquarters and begun our training, then we proceeded to head over to my parents house to train our supernatural side. After all our training we all just chilled. I went upstairs to get a board game from my room and when I looked on my bed there was a note, I rushed downstairs to show everyone.
"Look this was left on my bed"  I showed them the note
"This person will know who he's dealing with eventually" Jimin said and we all agreed
"I can't wait for the others to return so we can all kick some a$$ together" Mingyu said excited

Rose opened the letter and it said

I see your friends are back but not all your cousins, if I were you Choi twins I would keep a lookout on your friends and family wouldn't want them getting hurt now..... I will be seeing you guys when you least expect it"    
From: Unknown

"This person wouldn't dare try messing with us. There is nothing this person can do to us. Anyways let's just play the game and make a training plan and lookout plan tomorrow" Jennie stated

After we played our friend left and went home so did our cousins and my brother and I headed to bed. The next morning I got ready and left with my brother to go to school.  The entire day we all looked out for one another and came up with plans.

I'm sorry this one is short the other will be longer
