Your father and Levi's mother got married a week ago, so it's clear that Levi is your stepbrother.
Your parents are on their honeymoon so he has to look after and care for you.
Tonight the two of you were having dinner together, and at that time Levi saw you continuing to play your phone.
"Put the phone down and focus on eating."
He says in a cold but caring tone.
