Can anyone clear some confusion for me? The MIL is married into the family, right? And Cedric's father is grandpa's bloodline, the supposed next duke before Cedric?
MIL called Grandpa's wife "mother" so I was under the impression she's Grandpa's daughter somehow (not to mention their similarly prominent eyebrow) and so far it seems it's not like that
Edit: I read back to the first chapters and rediscovered that Grandpa only has sons, thus marriage to the Langton became grandchildren's responsibility. So yeah, our tsundere MILF is actually married into the family. She's just close to her MIL too. Guess that run in the family
