Damn even though I've been reading spoilers from the comments it still have my interest.
okay so here's the spoliers:
so the maid with the short hair is pouring poisonous tea. Aria tries to make her drink it, but the maid snitches and meile's head maid is blamed and she is then excecated for attempted murder of a noble. Aria is now seen as a saint. Then she finds out that her biological dad is a marquise in the neighboring country. He was in love with her mum but he had to leave cause. His mum (aria's grandma) was forcefully married to a prince, but her true love is the marquise and they shagged and had aria's dad. The prince thought aria's dad was his, but the truth came out and he exiled aria's dad and grandma. After finding out this she meets her aunt who is a judge. They talk and she finds out that the reason why she has her powers is because of her grandma drinking the water of the magical fountain (that's supposed to give you powers) when she was Preggo with aria's dad. After some time Meile tries to kill her dad to put the blame on aria. She fails at both. The count is paralyzed and aria is saved by the crown prince, who uses his power to go somewhere else and take a cab (for an alibi). They go to court and meile's found guilty and is put to jail. Aria saves her. Then Meile and Iris go to the neighboring country in hoping that the king will marry Iris. That fails and Meile and Iris are excecated for treason. Aria and the crown prince live their happy lives, have two kids. THE END
Can I have Aria? myghad these villainess stories has made it more difficult than choosing an husbando in every anime.
