Vivian finds herself possessing the body of a terminally ill female protagonist.

To avoid her tragic ending, Vivian approaches the villainess Rahel, the only one who holds the cure, and becomes her genuine friend.

“I’ve never once thought of you as a friend, Vivian.”

“Do you think you could do something like this with another guy?”

Wait—hold on a second.

You said she was a villainess?!

Why has my best friend suddenly become a man?!
