- Description from MTLNovel

I reincarnated as the wife of the cursed archduke in my own twisted novel.

As the author, I have a responsibility to fix this novel.

I have lifted the curse, which is the main problem of this story.

I thought my job was done. But when I was trying to go back, the archduke asked me, “Did you really think I wouldn’t know that you’re planning on returning to your fiance?”

‘My fiance?’

What I’m gonna do? He completely misunderstood the situation!

All I want is for him to please let me go home!

Reincarnating into another world without having to start from the bottom was certainly a good thing.

However, what if the first place you appear is inside a coffin?

This is what Qin Yuan experienced.

While he had boundless strength, he was already at the end of his age so he had to seal his body.

The only thing he could do was to leave with a Spiritual Body whose strength was extremely limited.

The good thing is that there is a system that suddenly appears.
