I Will Kill the Male Lead

I, Kwon Jin-ha, felt sick after reading a romantic novel. I was feeling all the emotions and sensations felt by the female protagonist "Elby"; we were connected. Due to the terrible pain and sadness, I went to the hospital several times, but the doctors said that nothing was wrong with my body. In the end, I sent an email to the novel's author. When I sent an email, all I got was a happy reply... "Do your job properly, Elby." I possessed the body of Elby in the novel. As soon as it happened, I got slapped by the male lead. Upon that, I had only one thought: "The male lead? It's over if I kill him, right?"
