The Cursed Villain is Obsessed With Me

Possessing the body of a supporting character who dies at the hand of the crazy second male lead, I decided to seek refuge to the Magic Tower. However, that d*mn Master of the Magic Tower suddenly picked up an unknown man?!
Glad to see a comrade, I followed and chased Claude, the new guy, and teased him badly.
“It’s amazing. It’s rare for a person to recognize me. They usually dies before they can even recognize me.”
“…… What?”
“Because I killed them all.”
That cute Claude is Ethan Clovis, the mad dog?!
I thought I was going to die just like this, but he suprisingly spared me temporarily and made me sign a contract.
“You’re signing this with me, Eunice Servita. When my curse is lifted, I’ll let you go neatly.”
I thought I had run away from this crazy guy, but instead, I had walked into the hands of a wild beast.
Can I break Ethan’s curse and survive safely?
——
“Do not forget that you promised to lift my curse. Even if it is just a facade, you must continue to stay by my side.”
Was I this good at taming mad dogs? I only accepted his eccentric temper and prevented his cursed magic from running wild.
“Hold my hand, Eunice. If I see you next to that bastard, I’m going to lose sight of my shallow reason and go crazy.”
It seems that the mad dog has been tamed too well. The guy who was going to kill me can’t let me go anymore. When I came to my senses, I was holding on to a crazy dog’s leash which he handed to me.
