Zi Xingxi shoved her away while secretary K called her a pervert. One can only imagine the fight that broke out between the two of them off-screen. Zi Han could hear them arguing in the background.
"Wake up and put on your pyjama top otherwise you will catch a cold. Better yet how about you wear that cute panda onesie of yours....," she said but Zi Han interrupted her as he got out of bed,
"It's still too hot for that. I won't be able to sleep."
That is to say, he wasn't refusing to wear it it's just that he was afraid it would be too hot.
"Ma you should stop forcing video calls. What if I was doing something inexplicable wouldn't it be embarrassing for the both of us," said Zi Han walking out of the closet while putting on his pyjama top.
Zi Xingxi spun her chair around with a sly smile before saying, "Then don't do inexplicable things... I heard you caused your grandfather trouble."
