How?

Ryu rose from his position, feeling refreshed. He swept a gaze toward Mae who had drifted off into a land of dreams and eventually decided on something. With a flip of his palm, he took out some beddings and pillows before laying her on the ground. 

As far as he was concerned, she was his woman now even if she wasn't his wife, and as such he wouldn't be so callous as to ignore her comfort. He didn't need to love her, but so long as she didn't betray him, anyone wanting to do harm to her would die beneath his wrath. This was simply his pride and his Dao Heart as a man seeking the pinnacle the world.
