A broken man who ended his own life finds himself reincarnated into the game he used to play. However, instead of becoming the protagonist or a powerful antagonist, fate places him in the role of a minor villain—a mere stepping stone for the protagonist in the game's first arc.

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.

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.
