Okay I'm not sure myself but:
-the emperor had a child w his younger sis (hector) then she fled to a small village
- Hector edwin and the twin meet in this village and lai witnesses the assasinst of the older sis wo took the arrow instead of the youngest
- Hector became prince and Ellen became bro w edwin bc people thought he was the witness( it was lai)
- lai became an assasin and was drug to to things and met Hector for the 2nd time they fell in love but lai didn't remember
- 2 year later Hector Ellen and edwin plot for the same thing without telling each other so there's a lot of misunderstanding
- lai found his memories back they all get vengeance and everyone is happy, the end !
Ok so someone please explain the plot to me because after reading all of that if felt as if my eyes just glided over the words.
