THIS IS FINALLY OUT I'M SO EXCITED!!

THE MEMORY THIEF:

Park Dayoung, the princess of the East Kingdom, the land of fire, has a different ability then what’s expected: rather than controlling fire, she can steal any memory from any person.

But she has another secret: she’s secretly meeting Byun Baekhyun, the enemy bodyguard who saved her life. But good things don’t last forever, and soon she is revealed by the rude, conceited princess Oh Eunjung.

Although she is to be exiled in one day, Dayoung finds a loophole in the plan- no one knows who she is secretly meeting. In order to protect Baekhyun, Dayoung steals all of his memories of the couple, but little does she know that this will send her on an adventure that could change the fate of the whole world.
