My Three Tyrant Brothers

Given a name from the days of the week As a slave she was called Wednesday When she was on the verge of death because of a small revolt
finally found you
Just overnight I was told I have three older brothers
Apparently I am the key to undo the curse on the Askanier Imperial Family
You need to be healthy enough for your clothes to feel tight to the point where you can no longer wear them That is your first task
Dont worry little kid All the bad guys will be punished by your brother
You look like a chick Small and weak Ill protect you
But why are the brothers that are called tyrants being so sweet to me
