Not their time yet

Xi Corporations HQ, 11:00 a.m. ;

"And you believe this crap?!", Zhi Xi read the piece of paper Xi Yuan had been earlier threatened with, a minute or two after he stepped into his ex-student's office and was infuriated by the contents scribbled into it. Furiously, he crumpled the piece of paper into his fist and threw it into the trash bin five feet away from him. "My sister would never do something like that, young man.", he said, his tone much calmer now than before. 

"I know, bro Xi.", Xi Yuan sighed, "Do you really think I'd doubt Xinghe? Never. And even if I would've, I knew better than discussing it with her brother. Her overprotective, loves-her-more-than-his-own-life, brother! I would've just confronted her. She is my fiancee. Anything she says, is the truth, for me. 

"But that's the problem. I cannot go to her with this. I can't."

"Why?", Zhi Xi furrowed his brows, confused.
