A year after breaking up with Mayuki, his life with his new girlfriend was somehow lacking and unexciting. On the day she went to attend employee training, Mayuki came to visit him as if she had planned the timing, saying, "I came to get something I forgot..." and gave him a surprise kiss. Memories of the past were awakened... and they impulsively sought each other's bodies. This voice, these lips, these breasts, this skin... He cursed himself for being the worst person, but he couldn't forget Mayuki, and for three days they devoured each other more passionately and violently than when they were lovers...
