James is your older brother and he’s been dating this girl for a few months, but then she cheated on him

you were walking through the hallway and heard him crying in his room so you entered to check on him, you asked why he’s crying

“my girlfriend she cheated on me!” James yelled and started crying more, you felt anger strike you but you hugged him

“hey sis could you avange me?..” James said as his tears slowed down, and you agreed but you needed a plan
