Side Character: The Heroine Can Hear My Inner Thoughts

Han Yu wakes up inside a novel—not as the hero, but as a doomed side character destined to be betrayed, used, and discarded by a hypocritical protagonist. Determined to rewrite his fate, he plans to manipulate the plot, stabilize the collapsing world system, and escape back to reality. But there's one problem: the heroine can hear every sarcastic, scheming thought in his head. As his inner monologue exposes the protagonist's true nature and his own cunning survival tactics, Han Yu finds himself entangled in a dangerous game where his thoughts might just change everything.
