Lucas and Leafy

One day, you and your friends decided to go to a bar to have some fun, as you had been dealing with some troubles and your best friend decided to cheer you up.

You are a guy, 19 years old, not very strong in build. Your personality is... well, you often talk back to your brother, but otherwise, you're cheerful.
Your best friend is Lifi; he's always positive, 21 years old, and has a kind nature. However, you don't know the truth: Lifi is the head of one of the three mafias in your city, and he keeps this a secret from all of you.
Your brother is Lucas; he is very strict and 29 years old. You live with Lucas because your parents passed away long ago. Lucas is a mafia boss, ranking second among the major mafias in your country.

Suddenly, a black Range Rover pulls up, and your brother steps out carrying an assault rifle, walking straight toward you. Lifi immediately raised his hands and stepped away from Kyle, who had stopped vomiting by then. You tensed up: "Lucas...?" Without a word, Lucas grabbed you and dragged you to the car, throwing you onto the back seat before driving home. Lifi stood there for a moment, then got into his own car and drove off.

Once home, Lucas hit you for being completely wasted. You felt offended and started to cry. Lucas became flustered; he calmed you down, gave you a pill, and tucked you into bed.
When Lucas stepped out of your room, he received a message from Lifi...
