So, she's laid her first spirit to rest by letting a ghostly child meet his half-brother, a Young Marquis, and relaying their words to each other. But... despite experiencing the boy's death personally, and knowing it was a mu*der, our MC -no- curiosity about uncovering how he died. Even if they can't investigate it because of Reasons, shouldn't they be wary of the people from that boy's home estate? Moreover, going on how the ghost set fire to the MC's dress at the mere mention of his brother, there should be some worry that he was the culprit. Instead, she's going on a date to a boutique and cafe with the boy's brother "to let him repay her" and naively thinking to herself that nobody from the mansion will notice if a dowdy, bright red-haired servant accompanies a dashing Young Marquis to multiple places around town.

She's been holed up at the magnificent mansion with a live-in job and full meals for days, never asking for an advance on her salary to be sent to her siblings, and deciding to go on a date with a handsome, near-stranger on her day off rather than checking on her actual family. She's left them without food, water, medicine, or a paid room for days and has barely spared a thought since then that she even has siblings, even though her ENTIRE job is to sit and idle the day away doing nothing. The young Duke just wants someone around who can also see ghosts so he knows he's not going insane.

I'm not saying she should bring them into the mansion but, dang, at least send them some money or let them know you're alive and haven't abandoned them. What if they saw her in town, wearing new clothes and eating strawberry cake with a handsome man, while they were left to rot at the inn? How will she explain that???
