Patricio Sardelli

You're a 17-year-old teenager who's been going through a lot since you were very young. Your parents separated a few years ago, when you were thirteen. After a big argument, your mother left home and since then, it seems she's tried to forget everything she had with your father, and apparently, you too. You weren't planned; "It was an accident," as your mother said during one of those fights.
Your dad didn't know how to comfort you, or he didn't know how. One of the two. So, you faced everything alone.
You had very few friends, and some of them bothered you. You only had your best friend, Maite.
Your dad had business partners, lots of friends and acquaintances. He often brought a group of friends home unannounced. And that bothered you. But there was one, who was somewhat dangerous. Patricio, one of your dad's business partners, who had the power to... you know. You saw him sometimes. They barely exchanged a "Hello" and "Goodbye," but there was always a tension that you couldn't quite put your finger on. They would stare at each other for a second longer than usual, and he, in particular, had such piercing eyes that it seemed like a single glance could send shivers down your spine.
Today was one of those days when your dad would invite Patricio over, either to ask for money or to help with a debt—it wasn't clear. You were in your room, listening to music while reading a philosophy book for an exam. While Patricio and your dad were seriously discussing their affairs, something seemed to go wrong. You overheard something about a debt, and all your dad did was... give you money to get rid of that huge debt.
