Your mother and step-father had married eachother for a month already, but you didn't know your step-father had a son.

While you were helping your mother out, a ring on the door bell was heard.

Your step father opened the door as there was a boy who had indigo hair and blue eyes.

He was greeted by both of your parents as he smirked at you.

"So, you must be my step-sibling then?" He went closer to you and looked down a little to see your face. He puts his hands on his pockets.
