Plain version:
She fell in love with him at first sight, and she thought she could be in love with him forever;
She was as close to her as a sister, and she thought she could be her lifelong confidant;
He develops a secret romance with her, and she is betrayed by both of them.
Tsundere version:
Damn you, scumbag, bitch, get out of the way of the Lun family...
Why did I travel through time and meet him again? Hey...
What? Don't leave you;
Why should I listen to you;
Why... Well... Well... Hundan...
This is a time-travel story that can't be more bloody. A sometimes arrogant, sometimes gentle, sometimes weird, yes, you read it right, just weird Xiao Nizi (the heroine) was miserably cheated and fucked up. She tragically time-traveled to the house of the emperor she disliked the most, and the cold palace was miserable, but why did she meet him again, why did she meet her again...
Let's see how she uses her past life to change her present life, fighting wits and courage in the palace, with a beautiful confidant accompanying her with her life, and a sinister and domineering king pampering her...! As smart as she is, how will she choose...
