Lilianne who?#-.-)
She's Torre's (MC's new appointed guard by the ML) fiance who ran away and has been seen in Suterana. She was denounced by her family thinking she's one of the girls who fell in love with Robin (Princess' fiance and a major flirt) despite having a fiance (due to the large amount of annulment cases by girls who were seduced by Robin). Well it seems like she has been "seduced" by Robin to kill ML.
I would certainly love me some spoilers right now ٩(๑❛ᴗ❛๑)۶
