The simplest being making sure there was something tasty ready when Lu Feng returned from work, and that their bed was extra cozy for him. Don't think he didn't know what being here with him meant. An Zhe would just have to make sure Lu Feng got plenty of rest afterwards. He was working so hard.

"Mmm. I like being safe." He moved to discreetly hold on to a bit of Lu Feng's coat. Being safe himself wasn't the only reason it was nice to see him there. There were no secret troubles to be encountering if he was loitering right here, after all. " ...and I like knowing you're safe, too."
