After the happy ending

Do you believe in time travel? Kisha Raids didn’t really believe in these things until the moment he found himself in the past the next day after a ghost summons. In the past, which was completely erased from his memories during an accident. You will soon realize the sad reason for things. What would you do if you knew in advance that you were going to lose the person who rewrote your story? Would you put up with it or fight your destiny? Once all the story is over, unfortunately there is one that comes sooner.
