Eponine and Cosette both work at the same downtown coffeeshop.
Eponine has been working there for a lot longer since she’s local to the area and it’s been her job since she was 17. Cosette started working there as a student in order to afford her off campus rent.
Throughout their time working together, Eponine ends up spending (too much) time with Cosette, helping her perfect latte art and sometimes laughing about made up stories for their late night customers. More often than not they end up talking about their lives in the backroom during their breaks or making out in Eponine’s car after their shifts.
