If fate allowed me to go back in time, just 30 days, I'll be sure to save you. I promise to you
Daewon and Soo-Yun are classmates in highschool. On the day Soo-Yun had her big chance to perform on stage, she was killed. After fighting with her killer, Daewon gets the second chance to rewrite fate: he goes back in time one month prior to this unfortunate event. Not knowing who the real killer is, he will have 30 days to figure it out and protect the girl he loved.
Can Daewon save his crush's life after he travels back in time? Or will he see his lover die a second time?
