The Princess Enters the Demonic Heart Trial

The iron-blooded female general So Gyeong-gyeong of the Daeyeon Empire dies on the battlefield and is reincarnated as the legitimate princess So Gyeong-gyeong of a small neighboring kingdom with the same name.

Wanting to find out how her family is living after her death, and why she died in the first place, she gladly accepts the marriage alliance proposed by Daeyeon’s crown prince to the small kingdom.

When she returns to the Daeyeon Empire, what she faces is her former life, now accused of treason, and all kinds of political enemies aiming for the crown princess position!

But this So Gyeong-gyeong has only rolled around battlefields for one or two days. This kind of danger can be handled easily.

What bothers her even more is Crown Prince Yong-gwol, who first threatened to use her, then suddenly starts treating her as tenderly as if they were lovers.

"Weren’t we just in a relationship where we were only using each other for mutual benefit?"
