Reason for his disappearance

"Tell me. Why were you completely unreachable yesterday?" Xiu Mei asked in a serious tone while sitting comfortably on the far end of the couch at the President's office. She kept her distance from the President who was sitting behind his office table while flashing a look of amusement to where she was seated.

She would sometimes avoid looking at his eyes and sometimes throw a glare in his direction. She couldn't help it. Lu Chen suddenly became too sticky with her this morning. 

He was still acting like a decent human after breakfast. But as soon as they've dropped of Lu Qiang at school, It was like he transformed into a different person. 

He didn't push her down or attacked her or anything but… his way of displaying affection undoubtedly became more obvious.
