The third year after my sister disappeared, I discovered the yellowing diary while sorting through her belongings.
As soon as I opened the first page, I touched the hidden time and space spell, and when I opened my eyes, I was transported to a battlefield in another world thousands of years ago.
In the smoke, I recognized at a glance that the silver-armored female general was my sister, but the man guarding her—
He is clearly my best brother in modern times, and the tacit understanding between the two of them fighting side by side stung my eyes.
In order to find out the truth, I disguised myself as a soldier and approached, but I heard rumors from the whole army:
"The general and the military advisor appeared at the same time three years ago. They are a God-given battlefield couple."
Three years ago, it was the day my sister disappeared.
