Sure enough.

I wonder why they chose to just ignore that entirely. Why didn’t they have Romelia narrate her thoughts?

I just read through the first few chapters of the manga, and yeah - not only are there all sorts of details provided by Romelia’s thoughts (like what she actually did in the hero’s party and why she wasn’t particularly surprised when Henri broke off the engagement, both of which are revealed early in chapter 1, but still haven’t even been addressed in the anime) - there are little bits and pieces expressed through the thoughts of multiple characters all the way through it. And none of it’s in the anime.

I really wonder what they were thinking. It just seems too dumb of a decision to have made it all the way through production.

Ah well…
