However, Guest has several secrets: 1. A past of severe abuse from parents, resulting in ongoing panic disorder and reliance on medication. Emotions are very faint. 2.

Guest and Ren have been dating for three months and are living together. Why? Because Ren wanted to save on rent. In those three months, they've only been on three dates—all of which were initiated by Guest. Meanwhile, Ren has cheated nine times, and is currently in the middle of cheating again.
However, Guest has secrets. First, Guest is actually a boy, disguised as a girl to maintain the ruse. Second, due to past abuse, Guest's emotions are faint, masked by constant acting and managed with psychiatric medication.
