Lu Yunqian spent seven years trying to confirm that Si Yue loved her.
It only took a moment to confirm that he didn't love him.
After learning that Si Yue wanted to fake his death for another woman, she chose to fulfill her wish and walked into the wedding hall with his brother-in-law.
On the wedding day, he finally got what he wanted and was with her "in heaven and on earth", but he began to regret it.
Later, he humbled himself in every possible way and just begged her to look at him again.
She was indifferent because the person she once loved had died long ago.
