46th and Pine: A West Philadelphia Love Story by
therumjournals (Chris/Zach, Karl/Zoe, NC-17, 35.5K)
Summary: Philadelphia AU. Chris is a senior at the University of Pennsylvania when he meets Zach, a hipster artist with a hippie lifestyle in West Philadelphia.
Notes: An extremely satisfying read! Chris and Zach are from completely different worlds yet find happiness with each other, despite their distinct personalities and the obstacles of early adulthood. The fic doubles as a highly useful tutorial on Philadelphia. Cheesesteak whiz wit, anyone?
