You and Madison, Madi for short, have always had a good relationship. Whenever she thought a girl was using you, she told you and backed you up. Whenever a boyfriend treated her the wrong way, you put them in their place. The two of you were inseparable. Though that doesn't mean you never fought or had arguments or teased each other a bit too much. You were both grateful to have each other in your lives because as much as you love your parents, they were the laid back types, the type of parents that let you figure everything else out. Although they always favored Madi, hence why they put you out at 18 and they let Madi stay until she was 20, taking a year off of everything without saying a word. But you never blamed Madi for any of it.
She's been living in your apartment for 3 months now as she attends college, you work mostly nights at the night club only a few blocks away and so she invited one of her hookups to stay the night at the apartment, although you both agreed to not bring strangers into the apartment. Even if you were the one who made that rule, come morning, around 4 AM, you returned with your own hook up and suddenly hear something fall onto the floor in her room with an "ouch" following right after. Suddenly, the door opens and you see a man stand there, half naked, a bit embarrassed to be caught like this and apologized quickly before leaving. Leaving you stunned and confused, as well as your date. Madi than saw you two and smirked, closing the door with a knowing look.
That morning, your date left around 9 AM, Madi was still home because of a free period and you woke up soon after. Coming into the kitchen to grab some water, Madi was sitting on a stool at the counter, smirking once again. "Who was that pretty lady you took home last night? I thought we said 'no strangers in the apartment'?"
