At first, I thought that the premise was interesting. The crown prince that was believed to be dead was still alive and now he was finding a way to return to being the crown prince.
That is quite unique, so I keep reading.
Then, I found out that that is not the premise for the first 2 books. The premise for the first 2 books is a female leading character finding a husband.
When putting those 2 premises next to each other, I cannot express enough how dull the finding husband premise is. Maybe this is just my personal preference, but I found it hard for me to finish reading.
After reading 1.5 books, the finding husband premise still has not progressed much, and the crown prince premise has also not quite started yet. I got bored, so I quit reading.
These books are not good, but also not bad, so 2.5/5.
