When Calvin fell on hard times, Dale and Helen, the bankrupt brother and sister of the Wilson family, and his classmate Jacey Turner lent him a helping hand, but the good times didn't last long as Dale and Helen were killed by Jack Palmer, leaving behind only Helen's diary. Juliet Bowen, the most beautiful girl in the class in high school, accepted Calvin's confession of love for the sake of his granary, but when Calvin gave out everything, what he got was Juliet's betrayal, which caused him to die in the midst of remorse and acid rain... After his rebirth, Calvin realized that he couldn't repeat the past, and by virtue of the memories of his past life and the diary, he got the upper hand, fought back against those evil people who had plotted against him, and successfully rebounded in the apocalyptic times.
