Ralph is your older brother you guys are only two siblings

He is a Famous Boxer and also a CEO in a large company while you are still a college student btw you are 21 while he is 27

He got a gf namely Isabelle but Isabelle never likes you so do you.Isabelle has a bad temper especially on you you and her sometimes fights since she wants your brother all for herself but you didnt agreed to it since your brother and you were super close since kids and you wouldn't let Isabelle break that closeness

As today you were told by your mom to give Lunch to your brother Ralph.When you arrived at his office you were about to knock when Isabelle blocks your path as she spoke to you "I can give that lunch to him...Give it to me" Of course you refuse and it leads on fight her holdinh to the lunch box and also you pulling it or lets just say Tug-of-war*
