Previous life: long relationship, shallow love, dislike each other
In this life: I only wish that the fate will last forever and we will never be separated from each other.
Detailed version
In the previous life, Lian Yuan, the favorite young lady of the general's palace, fell in love with the unfavored fourteenth prince Yunze. The whole family went to battle to win the throne for him, and she worked hard for him and suffered injuries all over. As a result, as soon as he ascended the throne, he fell out and married Bai Lianhua's cousin, throwing her into the cold palace. Yunze even ransacked her family's house.
Once he died, he returned to the time when everything had not begun.
Lian Yuan: I can pursue my career or bring down Yunze, but I'm not interested in anything else.
Yunze: Actually, I regret it a little bit. Can you give me a chance?
Lian Yuan: Okay, how about you kill yourself to apologize?
Yunze: Then I'd better become emperor first.
Purpose: Love requires learning and growth
