I Will Try To End The Male Lead

i, kwon jinha, began feeling sick after reading a romance novel. i became connected to all the emotions and sensations of the female lead, elvi. i even went to the hospital due to severe pain and sorrow but the result said there's nothing wrong with my body. so, i ended up sending an email to the novel's author, begging for the male lead to stop tormenting the female lead. but instead, all i got was a happy reply, “do your job properly, elvi”. i found myself possessed in elvi's body in the novel. i got slapped by the male lead as soon as i possessed elvi's body, upon that, i had only one thought, “the male lead? it's over if i kill him, right?”
