I'm a Villainous Daughter, so I'm going to keep the Last Boss - Vol. 1 Ch. 1

[SpecialProjectY]

Is she technically a guy in her past life?

Looks like no giga-booba before being a teen, so a guy./s

 

[SpecialProjectY]

Blonde man claiming to be prince Broke up with poor mentally unstable girl and then proceeds to steal her business and humiliate her in a public party with the girlfriend he cheated on the girl with.

Wouldn't call her "mentally unstable", she was kinda abused by her "father" by nitpicking her every mistakes and not being supportive, it's great she didn't went depressed with low self esteem, but somehow became stronger.

The rest checks out.

I am kinda confused about the father, I don't know if he is a good one who is just trying to push her to success or if he is a bad one who wants her to fail

Instead giving support, he nitpicked her faults, strangely it didn't lower her self esteem.

I like her father.
