Years spent sacrificing everything to feed my mother and younger sister. A garbage life earned by exploiting women's feelings, a twisted and tangled existence that eventually fell into the abyss. At the very moment I let go of everything, I opened my eyes to find myself back in 2015, ten years ago, when I was a first-year high school student. In this life, I'll become rich through honest work, study hard, live diligently, and be an excellent son and brother. From now on, I won't exploit the feelings of women around me; I'll simply be a good man. "Do you have a girlfriend?" "Jihun is different from other boys, more mature." "What's with your voice? Shouldn't you be attending an arts high school?" "Hello, oppa. I'm Jihyun's friend." But even though I'm just being kind, people around me won't leave me alone.
