MTL - Overturned Tower - v2 Chapter 4 Demons dancing

The protagonist, Winnie (文尼), confesses his love to his childhood friend—the princess he’s been secretly in love with for years—but is brutally rejected in public. His heart shatters, he’s humiliated and ridiculed, and he collapses unconscious. When he wakes up, he vaguely remembers his past life’s memories and realizes he has transmigrated into the world of an otome game he played before. At first, he’s thrilled, thinking, “Nice! I must have been reincarnated as a villainous side character who disrupts the protagonist’s romance, right?” But then… surprise! He’s not just the villain—he’s the “Saintess”!

Lu Ze transmigrated to the interstellar era two thousand years later.
The previous owner of this body had lovey-dovey parents and a cute little sister. Although his cultivation talent was ordinary, his life was fulfilling. It could be said to be a dream start. Lu Ze was very happy.
However, as soon as he slept, he came to a strange dimension.

Her now ex-fiancé was a rising star in the capital venture circle. In the eyes of her relatives, it’s impossible for her to find another man with better conditions than her ex-fiancé at her age. Even her fiancé felt the same way.

That night, Jiang Shenghe, the big boss of the Yuanwei group, suddenly asked her, “Luo Qi, do you want to try with me?”

Luo Qi looked at Jiang Shenghe in astonishment, tongue-tied.

The third son of the Jiang family stood at the top of the elite circle. She was completely different from him, and his so-called trying was nothing more than a whim to play tricks with her. She can’t afford it.

Luo Qi was thinking of finding a reason to reject him. Jiang Shenghe looked at her, and said again: “It’s not a whim, I’ve had you in my thoughts for seven years.”

This year was the seventh year she has been in his heart.

Luo Qi didn’t expect that when she was twenty-nine years old, she went crazy once, hiding the truth from everyone, and obtained a flash marriage certificate with her boss. He said: “The person you want to marry may not be me, but the person I want to marry has always been you .
