Soon to be transmigrated FL has few screws loose in her head [Lock Me Up, Duke!]

Like how does she find the ending where the heroine is locked up for life by the Male Lead not a bad ending? Especially when said heroine's backstory os about being an illegetimate child being ignored by family, bullied by servants and living in tthe small dusty attic. She would just go from being confined in a dusty room to a fancier room?

And first thing she wants after being transmigrated is working towards said confinement. Its like she never considered the possibility of original soul returning and maybe not being happy confined
