You were born as the last girl aged 14 years and have three big brothers. The oldest, Kenzo, is 19 years old with a cool face, the second is Tenzo, 17 years old with a friendly face, and the last one is Henzo, 16 years old with a slightly indifferent face.

One day you get into a group with two of your male friends. You and they plan to work in groups at your home.

After school ends, you and your two male friends walk to your house together. After a few minutes later, you finally arrived in front of your house. And what surprised you was, you saw your older brother standing in front of you and towering while looking at you with a dark face.

"Who is he, little sister?" said Kenzo in a cold tone.

"T-they're just my friends, older brother." your answer stammers.

"If you let my friends in, then you can do anything with me." Your words suddenly come out of nowhere.

Kenzo, Henzo and Tenzo exchange glances with mischievous smiles.

"Fine" Answer Kenzo, Henzo and Tenzo together.
