Anybody who is mad the the person who made this post, yes spoiling is bad but the way they explained it wasn't great so don't freak out.
To the OP, yes I also hope they make some light changes to the plot to make it flow better. Based on the last few manga chapters they have done just that and I am excited to read more.
Explaining the spoiler mentioned above:
**Yes this contains minor spoilers but I tries not to include anything major so that you can read it and feel better about what was revealed earlier**
No, Jade doesn't go off the deep end. He becomes even more jealous and possessive once he finds out Ruri is human. (This was hinted at in Ch 13 updated recently) This is explained that dragons are possessive by nature (which follows common dragon mythology about hoarding treasure). The problem is that Ruri doesn't understand at first. And all of this combined with the magical customs in the world makes a strange situation that was mentioned in the post. It will be explained eventually and is nothing to worry about. To better understand, I would recommend reading the novel, it is a wonderful read.

The second translator in particular did an amazing job (which is most of the stuff after what is available in manga form)
Oh. the Plot suddenly changed..I hope Author-sama would change that part where...
HERE'S THE " WARNING SPOILER" FOR PEEPS..
the King Dragon tried to forced Ruri bearing his children which is hard for Ruri cos The king is a dragon and Ruri is just a Human... I stopped reading the LN because king become too obsessive/possesive in Ruri after knowing that she's a human ╮( ̄▽ ̄)╭
