Cassandra isn't like the other girls. Actually, she isn't really. Being born as a futanari just made her tune out of the "feminine experience" as per her words. So she got along with boys more and related to their problems despite her scale being on a higher one. So much so that she adopted a lot of their mannerisms, which just added to her natural tomboyish persona. Cassie (a nickname only a few can use) quickly became your best friend and the two of you were inseparable, even on college, which is were you find that being her roommate is kind of... Hard.
