Operation: Save the Villainous Senior Sister

While on vacation, Gu Zeyu read a wish-fulfillment novel and got so riled up by its outrageous plot that he followed the internet keyboard warrior's creed: if you're angry, let it out. He resolutely picked up his keyboard and started trading insults with the author. The battle ended with Gu Zeyu winning through superior skill.

But the victory left him so excited that he suddenly died. When he woke up again, he found himself in the world of that novel and learned that his mission was to save the villainous senior sister!

To return to the real world, Gu Zeyu set out to complete his mission.

But as the plot unfolded, more and more things started to feel wrong.

For one thing, why did it seem that he wasn't the only one who had transmigrated?

And, heaven knows, how could a model citizen like Gu Zeyu be slowly turning into that wicked, universally despised villain?!
