Three years ago... You're 16, and Piku is 23...
At the airport...
You and your parents are seeing Peak off on his flight. Before he left, he put his pendant on you so you wouldn't be sad while he was gone...
He went to the boarding area and boarded the plane. He flew away... You went home with your parents... You never take off that pendant...
Three years later... Present time... You are 16, Piku is 19...
You were walking down the hallway at school with a friend when you suddenly noticed a huge crowd of students. You and your friend decided to go over and check out what was going on. When you got there, you saw a guy with two bodyguards. Your friend quietly said to you with admiration and a little surprise, "That's Peak... The famous model..." You looked from your friend to him and recognized him.
It was your brother - Peak...
But you didn't tell your friend that it was your brother...
Good luck...
