Others love it when the sky is clear, right? I don't. Others enjoy running around, right? I don't. On September 1, 2008, I became paralyzed from the waist down due to a traffic accident. Why is life so painful? I'd rather be dead. Just as I was thinking that, Sun-jae said to me: "Thank you for staying alive." Thanks to those words, I regained my will to live and started working hard again. For years, I lived only for Sun-jae. But then, like a sudden thunderstorm on a clear day, news arrived. Ryu Sun-jae is dead. ... No, it can't be... I should have protected him... At that moment, my watch suddenly triggered a time slip, and I returned to the summer of 2008. Since it was before the accident, my legs were perfectly fine. Wait, Sun-jae is at the school next door, isn't he? I have to protect Sun-jae. I have to change Sun-jae's future. No matter what.
