My Monster Secret: Actually, I Am

For Kuromine Asahi, honesty isn't just a virtue—it's an involuntary affliction. The high schooler possesses a constitution so fundamentally averse to falsehood that even the most trivial deception, from bluffing in a card game to harboring an innocuous rumor, proves utterly impossible. His transparent expressions and tell-all demeanor have made him a reliable, if predictable, friend to his classmates, but they have also rendered him completely ill-equipped for the one thing life suddenly demands of him: keeping a secret. That impossible burden comes in the form of Shiragami Youko, the ethereal, soft-spoken beauty who sits beside him in class. When Asahi accidentally stumbles upon her most guarded truth—that she is not merely a quiet, aloof girl, but a genuine vampire surviving in the human world—his world is turned upside down. The revelation places him at the center of a perilous and comedic tightrope act, where one slip of the tongue could expose Youko to a world that would never understand her. For a boy who wears every thought on his face, protecting her secret feels like a mission doomed from the start. Yet, as the pressure mounts, Asahi discovers that the line between duty and genuine affection begins to blur. Navigating a gauntlet of suspicious friends, bizarre classmates, and the daily absurdities of harboring a supernatural being, he must find a way to master the art of silence. In a life where lies are impossible, Asahi must learn that the most important truths are often the ones left unspoken—and that keeping a monster's secret might just be the key to winning her heart.
