Corvo and Jassamine (Discussion)

I was curious about how everyone feels about their relationship. I know it was more or less only hinted in the first game and outright stated in the sequel that yes he is actually Emily's father (the books call it a "terribly kept secret" which sounds very meta). But what's the majority view on the relationship?.

I was pretty okay with it until I read the book "Corvo Altano, The Royal Protector In Our Times: Part 02" Which states that he was initially Jessamine's "Royal Protector" when he was 19 and she was 12!. Then they apparently began a affair when he was 25 and she was 18.

Just wondered what the general consensus on this is.
