The Adopted Princess Hopes to Escape the Genre

A 24-year-old college student buried in assignments, Yoon Se-ah. When I open my eyes, I’m in an unfamiliar place, dressed in rags and standing in the rain.
In front of me appears a duke who, saying I resemble his lost daughter, wants to adopt me.
It seems I’ve somehow possessed a character in a regretful family story.
But then…
“Try calling me ‘big brother.’”
With a strange eldest brother.
“Your innocent and cute expression doesn’t work on me.”
“Pardon? I didn’t do anything….”
“It won’t work.”
The second brother, who only spouts nonsense, becomes obsessed with me.

Then, I meet potential male leads.
“An angel’s presence sparkles around you.”
Is this his way of introducing himself?
A candidate priest who looks just like an angel.
“You’re welcome to marry me.”
My childhood friend, who out of nowhere tells me I can marry him.
“Finally found you. Thanks to you, I spent a few extra hours in that pit.”
Even the Crown Prince, whom I purposely avoided, is searching for me.
“INTJ? I’d prefer to be an F.”
“Unless the archduke loses his memory, is reborn in a harmonious family, and develops healthy hobbies and relationships, changing his MBTI is difficult.”
Not even beating up the creator would help….
The northern archduke fixates on the MBTI I taught him without much thought.
Something is definitely off-kilter here.
Can I really accomplish my goal of securing a fortune before the real daughter returns, by finding the main male lead?
