With how much hate Gilbert is getting all the sudden and with the mom focusing on firing him and trying to avoid the MC from finding out about him or the rumors.
I have a feeling that Gilbert is going to mean something to the MC from her past life.. not so much as something like a love interest. Probably, something a long the lines of what it meant to 'be a commoner".
However, if that's not the case. I hope justice is served to his prickish self.
Edit: Also, still don't like the butler. No matter what his inner dialogue will state. The author just drew him to skeevy looking for me to trust him.
