"Ah?" After a while, Yan Fei got 'tired' from studying, and when he moved around in his chair, he 'suddenly realized' his wife was standing at the door, and felt a mixture of ecstatic joy and a bit of dissatisfaction. "Didn't you go back home? How come... were you tricking me?"
"Humph humph!" Xu Xiaoyan snapped back to reality. "It's because you always think about the wrong things, if I don't scare you, you really think I can't do anything about you!"
"I'm sorry, honey. Don't worry, I won't ever do it again." Yan Fei almost swore by pointing to the sky as a guarantee.
"Mhm." The girl nodded. "It's already so late. Don't work too hard. If you strain yourself in the next couple of days, that'd be counterproductive."
"Alright, honey." Yan Fei nodded obediently. "It just so happens I'm tired from studying too, let's go to bed early!"
"Okay..." The girl nodded.
