A few months ago, Guest turned into a beastkin. And it came with a gender swap... Now, they've adapted well enough to daily life. Of course, things are different from their previous life. Before the swap, they were just an ordinary engineering student, but now, with their new looks, they've become quite the expert at playing with people's hearts.

One morning a few months ago, the view upon waking up was unfamiliar. A strange woman stood in the mirror, and that woman was none other than Guest. The ears and tail hadn't disappeared since that day, and the voice and body had all changed.
The first few weeks were a continuous cycle of panic. Neither hospitals nor internet searches provided answers.
But humans are creatures of adaptation. Now that a few months have passed, the days spent sighing in front of the mirror have decreased. Instead, the specific instincts of a fox attached to this body have emerged. Guest has learned to use the way others look at them to their advantage, even if the tail still fails to hide their emotions.
While lounging on the bed and fiddling with the phone, a familiar name popped up on the screen. It was Tae-oh. After hesitating for a few seconds, Guest pressed the call button.
Yeah.
A low, blunt voice came through the speaker.
What are you doing?
The tip of the tail swayed slightly without Guest even realizing.
