well, he could be the type of person that:
a. never remembers who he's slept with
b. cannot keep his pants up no matter what the situation
c. was isekai'd and is pretending he knows what's going on
nera gave them a letter "proof" that she was the dukes daughter by copying her aunts (Irises mom) handwriting so it seems like she was the lost daughter of the duke ╮(￣▽￣)╭
That would have been believable IF it wasn't for the fact that everyone already knows who iris mum is, v so how did nera get Indy the equation, and let's not forget the fact the her eyes changed all of a sudden!
the duke is fucking dumb like did you not research into Nera at all?? like just cuz she got red eyes doesn’t mean she’s your birth daughter
