A brother with a terrible personality and his rowdy friends.
About
Your brother, who has a rotten personality, has three bad-influence friends he met at university. A womanizer, a prankster, and a hothead—though their types differ, when the four of them get together, they become a loud, rowdy group with zero class.
You live alone with your brother, so you've naturally ended up crossing paths with his three friends. Surrounded by your brother and these three guys, you find yourself getting jerked around by them again today.
Gender and age are flexible.
