Today, I am a substitute for your fiancee. Tomorrow, I’ll become your sister-in-law!

Mu Mingtang is the substitute of the male lead’s first love. After she lost her family, she was adopted by the Jiang family and eventually became engaged to the male lead, the Prince of Jin.

Understanding very well that she was only a substitute, she removed her claws and fangs and turned herself into an imitation of the Prince of Jin’s first love. She couldn’t speak or laugh as she wished, she was prepared to live in the shadow of another woman for her entire life… until one day, the real Miss Jiang returned.

The real Miss Jiang was reborn. When she learned that she was the male love’s first love, she immediately returned to fight for her engagement and identity.

In order to please his first love, the Prince of Jin gave the substitute to the Prince of Qiyang, who had become a dying madman. She was just a low-quality fake, anyway. If she dared to anger his first love, he would turn her into a childless and powerless widow for the rest of her life.

Mu Mingtang, the target of their mockery, finally snapped: Okay, since you gave me to another man, I’ll make you bow and call me sister-in-law!

However, none of them expected the Prince of Qiyang, the God of War, to actually wake up!

Xie Xuanchen is the son of the late emperor. The whole world once trembled beneath his feet, but one day, for a reason unknown to even Xie Xuanchen himself, his nature suddenly changed. He became cruel and bloodthirsty, leaving his father with no choice but to pass the throne to his uncle.

Eventually, Xie Xuanchen was unable to resist the illness and fell into a coma.

When he woke up again, there was a beauty standing before his bed, looking at him in surprise. Then, for the sake of his domineering little princess, he revived his name as the God of War, reclaimed the throne, and united the world.

I once captured the world to satisfy my own ambition. Now, you are the reason for my ambition.

He Bai won the lottery, became rich, and reached the pinnacle of life. Then, he inadvertently took a picture of the Film Emperor Di Qiuhe being killed. And after reporting this case to the police, he was reborn in a midst of confusion.

He Bai: I don’t have any horrible relatives to abuse. Why was I reborn?

Di Qiuhe: But I do.

He Bai: I also haven’t been betrayed or harmed by anyone. Why was I reborn?

Di Qiuhe: But I have.

He Bai: I just want to have some money to live freely and eat well. I already achieved that goal, so why was I reborn?

Di Qiuhe: I have money, but don’t live freely or well.

He Bai angrily flips the table: So what’s the use of my rebirth! Just to make me suffer again?!

Di Qiuhe (Holding and Touching He Bai): Be my lover, you’re only responsible for eating “lollipops,” you won’t eat any bitterness.

He Bai: Leave!

So basically, this is a sweet story of a naive and cute person who goes back to the past, flaps his little butterfly wings, and helps the man who used to be last life’s big Film Emperor, but in this life, is still a miserable Great Devil King, to walk towards the pinnacle of life (while also dragging someone home)!
