Her goal is pretty clear - she wants a lot of money and not be poor like she was in her previous life. She also wants to live, so she has to make friends with her grandpa's family and solve the issues with her inheritance since she is basically robbing them blind otherwise and they would kill her for that. A bit later she also realizes that she actually wants to have a happy family since her previous life's family wasn't a good one.
So all in all she just wants to be happy, rich and alive to actually to enjoy it. Not a bad goal, no?
Thanks for the summary I appreciate it!
The art is lovely but I'm kinda losing motivation to keep reading like what's the goal here (〜￣△￣)〜
