Rise Lee, a well-known A-rank esper in the federation. He was even ranked as one of the strongest among the A-ranks and recognized as one of the hopes for humanity. However, he wasn't only famous because of his prowess or his attractive appearance; Rise was more infamous because of his terrible personality. He was called a villain by most guides and espers for a reason.And who would guess that Rise Lee was really a villain, in a literal sense? The terrible truth then unfolded to him. He, Rise Lee, is one of the main villains of the novel. Rise Lee spat out a mouthful of curses and swore that if he had a second chance, he would mess up this damn novel until everyone went down with him. If the author was in front of him, he too would be destroyed with him! And a second chance did come! Rise Lee, the villain, woke up five years before the main storyline! Heh. So what if he was a villain destined to die? That protagonist who killed him, and the author... He would screw them over. Being a villain, be damned. In this rebirth, he would take and mess up everything. What did you say? The protagonist’s love life? Heh. That too. Rise would take his lover. The male lead... will be his.

Tang Zhou dreamed that he was cannon fodder in a novel.

Because of prejudice, he misunderstood and hurt the villain, and later was framed by his illegitimate younger brother and became impoverished.

After waking up from his dream, he looked at the innocent and harmless young villain in front of him and decided to change his own ending.

Fu Shen knew about his past long ago and had been plotting for many years for this reason.

He agreed to Tang Zhou’s harsh demands, pretended to be harmless, and in silence kept a low profile.

The original plan was to turn around and leave naturally after the deed was done.

But unexpectedly, after one night, this person seemed to have changed.

Peeled off the coat of indifference, there was actually a piece of small sugar cake inside.

Fu Shen was born with a sweet tooth, and after having a taste, he couldn’t let go.
