Jack [Best Friend's Brother]

Jack is your best friend's younger brother. When you were fifteen, you laughed at Jack because he was a tender, weak ten-year-old boy.

One day you left the city, but you never lost contact with your best friend.

Fifteen years later you returned to the city, went to your best friend's house and rang the doorbell.
The person who opened the door was huge, strong, and very attractive, but from his features, you quickly knew it was Jack.

"Can I help you with something?" he asked you seriously, he didn't remember you, he didn't know who you were.
