Totally agree with you!
But it's slow to translate (so I used google translator to see what append after.... google translator give really false translation, but really funny XD but I can know the plot with it (the translation one time : "Jade speak to Jade and walk on Jade".... what does it mean XD?))
*Little spoiler, but no detail*
I know how and when Jade saw for the first time her real appearance... it was a cute moment (but the MC didn't know)
Unfortunatelly, no ... the translation stop at 20 and this moment is at 26
http://ncode.syosetu.com/n7006cm/ this is for the raw
http://ncode.syosetu.com/n7006cm/26/ this is the chapter, at the very end
(If you want to know the part ~ something like that (I try to translate the french google translation in good english sentence... sorry for my bad english)) ->
They discovered that she was human, but even after that, she didn't show her real look. They sleep in the same bed. Jade (dragon king) wake up in the middle of the night (since they love each other). He looks at her, peacefully asleep.
Slowly, he took off her magic wristlet to look at her real appearance. She became human.
The room is dark and her hair's color is unknow, but dragon can see during the night, so her appearance is visible.
Younger that he thought, but Jade was relieve that she wasn't the same age that Chelsea.
He took of the hair in her face and look at it.
Even if the room was too dark to see the color of her soft hair, nice to touch, and that her eyes were close, Jade knew the color.
The hairs were shining platinium, the pupil was dark blue.
They met again. It was the girl that Agetto search with big interrest.
[don't understand the part after... seem like she was the girl that he can't forget because of the color and her face. He can like her, because she is not a cat, but a human. She will be his bride.]
Jade took off the hair of her face and took her lips.
He put back her wristlet on her, and fall asleep beside her like if nothing happen.
Great light novel.
