This drama has the same vibes as KDrama, Again My Life (AML). I'm not trying to say it copied AML, it will not have time to do it since both were released in the same year. Just how the whole story delivers, etc. I don't think this drama is bad. It is not good, but not bad either. I still continue watching it, even though not sure if I'm able to finish it.
None of these dramas are better than one another, in my opinion. But, since the main antagonist in this drama is way cooler than AML, while sadly the main protagonist is way poorer..... AML is more "watchable" for me.

At first, I thought, this drama is making sense, by making Lu An Ran overwhelmed by Mu Ze (MZ). LAR is only a merchant, while MZ is a King (politician), and she has to compete with MZ in the political area that is not her expertise.... But wait, she's the leader of her clan, she is supposed to be, at least, not doing what she's been doing in the drama so far. She can't even deal with her own brother

Just like AML, the drama only informs the viewer of some important events. Like the death of LAR's mother, her little sister's affection for MZ's personal assistant, her brother becoming a general, her brother's death, her son's death, the death of her brother, the death of all her family members, her little sister's betrayal and last, MZ kill the 9th prince. I think the writer thinks (or maybe he wants? But why?) that he has to stick to the timeline in the "original time pace". The writer kinda forgets that if something happened that changes the past, the future will change too. That means, if MZ needs more time to get married, or to at least take her as his ally, his time in the future to become a king will be delayed too. With all those details, the writer can play to extend or shorten the timeline of those events.

I can't stand on her way to deal MZ, just too reckless and damaging. Her "political" ways in her family, like during the internal leadership struggle and her mother's poisoning case, are quite smart. Her way to get away with the wedding is genius!!!
But, other than that, each of her steps is just too reckless. Like when she chooses to exchange the test page of a scholar and make him fail the test. She even can't do anything when the scholar rejected her offer (while he wants to go back to his hometown due to his disappointment)... shouldn't a merchant be great at making deals?
All that scholar needs is to improve his family status, I wondered why doesn't she discuss the condition with the scholar? He might willingly give up if she can successfully deal with him. She can offer him a position to help her with her business while he is waiting to rejoin the test next year.

I can't find why LAR thinks that the way to redeem her guilt is by revealing the real test result... he is DEAD!! Am I the only one who can kill myself if my actions caused someone to take their own life? Not to mention in a very gruesome way.
While Kim Hee Woo collected as much as allies as he can, LAR choose to do it herself even though she can't, I wonder why LAR always rejected the 9th Prince's offer to help her.

In the end, the only thing LAR can change so far is that she doesn't have to marry MZ, and her mother is alive. But, MZ wants to marry LAR to take advantage of her ability to build a warship, what's the point of the second change of life if in the end she still does what he needed her to? With all those credits, MZ will still become a king.
I think it might be better if LAR is able to make MZ lose his credits one by one. And without all those credits, he fails to become a King. Like what happened in AML, where Hee Woo imprison Jo Tae Sub's allies one by one, which made JTS lose his grip and power.
