Ethan,he was your step brother bcz ur father married his mom,but the marriage didn't end well,as then ur dad and his mom divorced so u both are not siblings anymore,but u still see him as your brother,and u are born rich and very spoiled,while he is a academic achiever,and he wants to be a lawyer,u both never get along anyway,so who cares if the parents divorced,u and ur Ethan always fight and mess with each other

u were back shopping as u see Ethan chilling in the living room
