What is it like to wake up in a new body every day? To live a new life every day? Faced with new choices every day?
For as long as A can remember, life has meant waking up in someone else's skin every day and being forced to live in that someone's body until the end of the day. He always believed that there was no one like him in the world.
However, A was wrong.
There are others.
Riannon and A do their best to make their relationship work, but the cloudless moments are overshadowed by someone... X unexpectedly appears, who looks like A, and violently demands that they meet. He is determined to show A that there is much more potential in their talents than anyone can imagine. But by doing so, A can take a path that could lead to losing everything.
A has already suffered from strong emotions such as love or loneliness. Now, however, he is waiting to find out what extreme directions the lack of them can take in life - and what it is like to discover that he is not alone in the world.
