Reborn into the villain of his sister’s favorite romance novel, William assumes the identity of Asterius, the god of fate, and is forced to follow the plot of the original novel. But when he reaches the end of the epilogue, he isn’t allowed to go home. Unknown to him, he’s greatly changed the plot of the original, because the cold and distant Demon Prince is now in love with him!

With the epilogue now long gone, he has to quickly adapt to being permanently stuck as Asterius, except there are a few problems.
1 – He’s been stripped of his godhood and no longer has any of his powers.
2 – There’s a very dangerous immortal god hunting him down.
3 – The System has stopped working.
[4 – He might be a little in love with a demon].
