Can you recommend some poignant transmigration novels?

I hope to know a poignant and beautiful time-travel novel. The more tragic the better. It would be best if the female protagonist was forced to return to the modern world in the end.
Hopefully, the story was written by an author with a deep literary foundation. The description was very detailed, and between the lines, there was a helpless sadness. It was a poignant fairy tale. The male lead could die or not, but it had to be at least a disaster, almost separating him from life and death.
In the end, the female protagonist remembered all of this with heartache.
(Note: Not only must it be sad, but it must also be beautiful.) Poignant and beautiful, this is the most important thing!
I don't know why I'm so interested in the dead thing. Isn't it a little abnormal? 555~（T^T）
Thank you, friends who like to wear clothes, but I firmly refuse to wear clothes!

" I recommend " Wolf Concubine: Demon Dance Under the Heavens " to you. This Xianxia novel tells the story of a female history teacher who transmigrated to the Mongol Empire and eventually became a wolf concubine who hid her name from the world. It was full of poignant and moving elements, making people feel complicated after reading it. I hope you like my recommendation.😘
