I prefer full chapters, if it's not too inconvenient!
As far as our ML here having two prior marriages, I figured if they were both separate and loveless but he respected them and treated them well, I'd be ok with it.
But like, to only have a "faint impression" of your first wife? So he didn't even try to establish a better relationship with her? Learn her likes and dislikes? Try to break through her carefully crafted persona?? Did the queen not have any responsibilities other than bearing an heir, so he could at least think of her being a competent and devoted queen?? Like, the second wife's situation couldn't be helped, but the first wife...I mean, c'mon.
Could he not have done it so that it would just be a prolonged engagement with no marriage at the end? That way, they don't have to divorce if Yui wants to marry someone else in the future...
