Although what Mireia was bad (calling it bad is an understatement) but she atleast realised the consequences of her actions, like the acted because of her fake letter and commited suicide and his sister couldn't attend the academy.

But this one here is pure evil. Although what Mireia was bad (calling it bad is an understatement) but she atleast realised how her actions affected others, like the boy who loved Lina, but acted because of Mireia's fake letter and later commited suicide and his sister couldn't attend the academy.

But this one her is pure evil. Ruby's actions are abominable, acting as a friend for so long and using the perks, connections and status of being Lina's friend while spreading bad rumours about her and bring her downfall. She doesn't seem to have a single shred of guilt for backstabbing her friend of many years!
