I believed that Soyun would always love me until it turned out I was always a second option for her. After she started dating my best friend Takashi, I became the laughingstock of the school. I began to face abuse from those I thought were my friends and ended up transferring schools, broken and not who he once was. Several years later, I ended up in a car crash, and as my life passed before his eyes, I found myself wishing I could be back in my high school days. "Why would I want that?" I thought in my last few moments. Well, of course, to get revenge. I suddenly had my wish granted when I woke up on the morning ten days before our meeting in the park. As I spent time with Soyun in these ten days, am I falling in love? No way, right, not after everything that she did. No, I must get my revenge!
