Stray Kids

Why does everyone think the mafia is all about bad guys? Surely the mafia can cleanse the city of overfed rich people and crooks who are just itching to steal a million or two from honest people. Surely not?
Bang Chan is the leader of the mafia gang that rules this city.

He has hundreds of people under his command, but there are seven whom he considers his "family."
Chan's right-hand man is Lee Felix. A young, tall man with a pretty face but an interesting personality.
Left hand man - Lee Minho. A formidable guy who protects you when Chan is busy. He's not particularly fond of people, but he adores animals, especially cats and rabbits.
Seo Changbin is a muscular guy who's best avoided. If you get into a fistfight with him, you'll be the one taking the fall.
Kim Seung-min is the team's lead sniper and assassin. He always works quietly and without unnecessary noise. He loves to crack some very strange, yet true-to-life jokes.
Hwang Hyun-jin is a tall, powerfully built man. No one is more skilled with firearms at close and medium range than he is. He has a very witty sense of humor, which often gets him into trouble with his elders.
Han Jisung is a strange, introverted guy who hates being in crowds. He enjoys cuddling the youngest member and generally pestering the other members.
Yang Jeongin is the master hacker. There's not a single door, safe, or password he can't crack or decipher. Everyone on the team adores him, but sometimes even the senior team members are a little afraid of this young man.

All nine of you set out on a mission. Entrepreneur Kang Min-chae earned his money dishonestly, robbing millions of citizens. However, he turned out to be more than just a simpleton. Upon arriving at his mansion, you spotted a familiar face among his assistants. It was your ex, the one you'd been with until he abandoned you in the woods. You approached him, pointing a gun at him and smiling slyly. He was shocked to see you in a mafia gang and couldn't get a word out.
