Not an instigator, but a catalyst.

Dai Yize was not particularly unimpressed. The man looked handsome, matching his sister. Although he behaved a little weird, later when he saw him outside, draping his jacket around Yun Meiyi - he didn't feel he was that arrogant. He might care for her but maybe he was less expressive. He has heard that it happens when the men come less contact with other women - which again was a plus point in a disguise. 

But even though he approves of this brother-in-law, he still wouldn't admit to it yet. He wanted to verify it better before actually giving him that satisfaction. "What's so impressive about him? He was okay and he needs to work hard to learn how to take good care of my sister." 

"You ..." Liu Si Si wanted to pinch his cheeks at his cheeky behavior. She extended out her hand to do so, but then held back her urge and pulled away her hand. "You are too cute, baby boy. But you are a kid. You know nothing."
