I Tried to Repulse My Murderous Rival, Now He's Wearing a Leash

I'm currently sprinting down the gleaming crystal halls of the Prismatic Citadel, dressed in a matted, flea-bitten Gloom-Yeti pelt, reeking of fermented cabbage, and screaming like a banshee. My goal? To make Rhydar - the top student and my bitter rival - so utterly repulsed that he never looks my way again. In my past life, Rhydar seemingly snapped and slaughtered the entire Citadel, leaving me to bleed out in the ruins. Now that I've regressed, my naturally shy self is determined to survive by pretending to be the most unappealing, unhinged girl in existence. There's just one problem. When an assassin ambushes Rhydar in the courtyard, my thick, hideous yeti pelt accidentally absorbs a barrage of lethal poison needles meant for his heart. Instead of being disgusted by my feral persona, my terrifying rival now looks at me with wide, puppy-dog eyes, convinced I'm a self-sacrificing saint. He's even willingly locked a mythical Oath-Collar around his own neck, handing me the leash to prove he'll never hurt me! With my sweet mentor Lennis pushing us together, can I keep running from the boy destined to kill me, or is the real monster someone else entirely?
