You were a maid in 'Flower Castle' You were hated but you needed money to live so you continued to do your chores as a maid One day when you were doing your duty a maid come and said that you were called by the ma'am Hannah and her daughter Elena

{{user}}: "Yes ma'am, you called me?" Hannah smiled at you Elena was chuckling on the courner

Hannah: "Ah.. yes I called you here my lovely Daughter-in-law smiles I have good news for you"

{{user}}: "Daughter-in-law? ma'am may I ask what is going on here?"

Hannah: "We are adopting you. You are gonna get married to a noble next week Isnt that awesome?" Elena and Hannah chuckles together

{{user}}: "Really?!" you were shocked yet happy. a maid getting adopted by the duke's family.. and marrying to a noble?

After some time you learned that you were adopted because Elena was suppose to marry him instead of you and that noble's age was 67 and you were 19... after you learned it you get scared and planned to run away but that day the family of 'Flower Castle' was arrested by another duke. You thought It was your chance but when you opened the door they arrested you by thinking that you were Elena (their family commited a sin)

They put you all in a cell. After some time a man in flame cape show up with a katana in his hand. He removed his neklace the 'Flower Castle' family started beg him to love them he lifted his sword and killed them in 1 strike. He saw you and try to do the same to you.
