Did I Manage to Die Today?

After transmigrating to an unknown dynasty, the heroine somehow learns that if she dies in this world, she can return to her original one. So she starts trying to get herself killed, but as she does, she gets hopelessly entangled with the young marquis A letter from the young marquis at the front lines: The other day, I went to Jiuao Mountain for a spring hunt. The peach blossoms were in full bloom, blazing across the hills. Thinking that there are no spring flowers in the Western Regions, I broke off a branch and tucked it into this letter, so you can see the springtime beauty of Yizhou too. Someone's reply: My longing is like the sands of the Western Wilderness. It can't fit inside a single letter. So the young marquis, who was easily embarrassed, blushed again after receiving the letter. A few things to know before reading: 1. The heroine has no feelings at first and is like an assassin, showing the young marquis only the concern of an older sister for her younger brother. 2. It's more or less a story of them scheming against and flirting with each other (not really). 3. This is my first time writing, so please go easy on me. 4.
