24 Hours of Great Sadness

Yamei’s father was brutally killed by a man in black. When he woke up, his father was standing in front of him alive. She thought it was just a nightmare of hers, but she didn't know that the experience after waking up was exactly the same as in the dream. At night, her father was brutally murdered by men in black again, and Yami also woke up from her dream again. Is this a gift from God or a joke from the god of death? His father was killed countless times. Yami woke up infinitely and witnessed his father's tragic death again and again. The only thing Yami can do is to look for clues in a repeated day to find out the murderer of his father and break this cycle.
