Himegoto Kakushigoto - Ch. 3 - Want to make a bet?

[suica]

It's totally weird how both the families are not acting as bitter as I thought they'd be. They're more like "Hahaha.. So our man had another family behind our back? Well that sucks. We still love him tho." But I'm more interested in how the audience gonna react to the incest ending like they never saw it coming.

I assume it's because the official marriage was arranged and the families were rich, so having an affair is considered normal. Look at how old money Americans have mistresses and boyfriends in their own arranged marriages, or how Prince Charles and Diana both had side arrangements.
