In recent months, Shi Yuhuan has spent every sleepless night going through his grandfather's old investigation files, reading them over and over again.
What he looked at the most was a section about his grandfather's trip to Korea from more than forty years ago.
Originally, the trip was to Korea, but for some inexplicable reason, he returned home ahead of schedule.
It was said that on the day he came back, he saw grandma with the old butler; in a fit of anger, he murdered grandma, the butler, and all the servants who knew the truth at the time.
However, the story that was put out was that the grandma had unintentionally drowned in the pool.
But what is the actual truth?
Did something really happen between grandma and the butler? When this rumor came out, no one believed it. Everyone said that the grandma loved grandpa very much and it was impossible for her to have something going on with the butler. So, how did things actually unfold?
