Public display of affection

Ye Zexian did not want to question his brother like this but he couldn't help it. Being the only one without a kid would be really hard on his brother, what if his wife started despising him? 

When Ye Liu heard his brother's words, he was stunned and then his face turned as red as cooked crab. He pursed his lips before saying, "It's fine. My wife does not mind it and having a child or not it's not something we can decide brother." He did not tell Ye Zexian that he was poisoned by that bastard Qiu Bai. If he told Ye Zexian that his body was affected in a such way that he could not have a child, then his brother would worry about him even more.
