While performing a mission as a top agent of the Information Guild, I got stabbed in the chest by a sword. I thought I was definitely dead… I returned to the hellish orphanage days when I was 8?! “Hello, I’m Dana!” Just then, the youngest princess of the Elad Duke family appeared in front of me. In order to not repeat the regrets of my past life, I took care of Diana and tried to send the kid off to the Elad Duke… Did I treat her too well? “You’re beautiful, Sister! My princess! I’ll protect you!” Diana, who doesn’t want to leave me even for a moment, and “Am I such an unreliable adult to you?” “I told you clearly that looks aren’t everything in a man!” The Elad Duke and the second son, who are indifferent to anyone but their family, and even the first son, who is famous for being cold, are strange! Why is everyone fixated on me when I monopolized Diana’s favor? The full-fledged webtoon version of Heeyoon's <Everyone Was Obsessed With Me After I Became the Youngest Princess's Favorite!
