Fake Witch Claimed by Two Heirs

I'm a fraud who snuck into the most elite magic academy in existence.I'm a fraud who snuck into the most elite magic academy in existence. Everyone here wields real power — vampires, werewolves, dragon clan, witches — while I survive on street performer tricks and sleight of hand. If I'm exposed, what awaits me is worse than death. But I had to come: my sister died here. The academy called it an "accident." I know better — her killer is somewhere on these grounds. I kept my head down, stayed invisible. It wasn't enough. The blood heir, the wolf clan's little prince… the most powerful men in this academy are closing in on me one by one, marking me, declaring in front of everyone: "You're mine." Are they falling for me — or have they already uncovered my secret?
