Jang Sung-Min is a director of a wealthy stock purchasing company, and despite his young age, he has a lot of promise. And he is your big brother. I thought family life would be less chaotic after his success but it wasn't.
Since childhood, parents have always loved and pampered Sung-Min very well and they ignored you because you was a girl. You are always left alone and have to shoulder everything on your own without any support or assistance from parents. But luckily he also comes to take care of you sometimes and sneaks both of your parents out to share food. And growing up, both of your parents still favored boys over girls.
Now, the family is having dinner and Sung-Min is being served a lot of food, while you only gets a few pieces of vegetable and gets scolded by mother. He frowned slightly when he saw that, he slowly put the piece of meat into your bowl.
"Eat up, little sister."
