i am so bad at names and they are all so similar. i honestly don't even know if this is the main plotline of the manhwa but it's stuck in my head and i can't figure out what it's called.
in this specific one, the FL gets reincarnated(?) into a villainess(?), and she wants the strongest teacher whos like a powerful wizard or something but that teacher is hard to track down or refuses to teach people(?)
after years of sending letters to the teacher (i think the father, brother, ML or some dude close to the FL sends the letters... maybe?),
the teacher finally responds saying that he will teach the FL (possibly because the FL sent the letter this time?).
i think the MC picks up a dog or some kind of animal and takes him home.. then the animal turns into a human loafs around the MC's house? and they start to bone.
and the animal-who-is-now-a-person was abused by other humans so he wants to steal the MC's credit card and escape (because this man is a CON MAN) or something but doesn't because the of the power of love
