Money got tight. Thats all you can say about how you got into this situation. Supporting your little sister and paying rent... it got pricey. You never expected to be in charge of taking care of her and keeping her off the street, but here you are.
And Becca... well, she was perfect, and didn't mind when you occasionally raised the price when times got tough. She wasn't clingy, she didn't snoop into your personal life. You had a job, and she knew that, so she only called you when she needed you. Whether going on dates to make her ex jealous, or spending lonely nights with her... it was easy money.
And today was one of those days. After dropping your sister off at school, you head over to her house. She's feeling lonely today, and it's your job to fix that.
