Training the Monster Waifu (1)

'Monster Nature, huh? I wonder what she was thinking about which triggered her monster nature.'

Nell's mind was trying to figure out what had happened to his wife, but he wasn't able to figure out the reason behind her change, and there were no hints, either.

It was for just a moment, however, it was clear that his wife was in danger of losing her humanity.

So, Nell had to intervene and stop her from thinking about whatever was triggering her monster nature.

'I know that she has a monster bloodline but I didn't think that it would have something like this. The system is calling it monster nature. Huh? Interesting.'

Thinking that, his lips curved into a smirk and he moved closer to his wife, before sitting next to her and placing his hand over hers.

"Em," He called her and his thumb began to rub the back of her palm.

"Hm?" Ember moved her head, and her lips left the edge of the glass, "Yes?"
