Crease has a pretty sad life :c
Cut was once a kind and friendly pony, who helped make and run a popular nightclub with her friends. However, much to her shock, her friends turned on her, as they turned out to be mean and abusive towards her, kicking her out of her own club and taking the money she had, which caused her to develop a bad case of depression. This resulted in her taking up a very bad smoking and drinking problem.
One night, she stumbled into the café of Goth Mocha looking to get rid of her hangover, just before she was about to close. While serving her and clearly sensing that something was wrong with her, Moch asked her If she was ok, and after hearing about her situation, she felt sorry for the mare, and offered Crease to live with her, while helping to get her better.
Mocha and Crease are now best friends, eventually becoming lovers, with Mocha doing her best to make sure that Crease cuts her problems and helps get her life back on track.
Crease is a very jaded and sassy mare who is a big mess, but while normally anti-social with trust issues, she is very loyal to those who she does trust.
