According to Zhang Dashan, if he didn't come back, he would let He Hongjuan remarry Chen Erniu as a way to repay the Chen family for raising him!
If both of them knew this, they probably wouldn't be troubled by the situation.
With Zhang Dashan's words before he left, plus the fact that he never slept with He Hongjuan, it wouldn't be a problem at all for her to remarry Chen Erniu.
At most, people in the village might gossip behind their backs, but openly no one would accuse them of impropriety since, essentially, He Hongjuan and Zhang Dashan were not truly husband and wife!
At this point, Chen Erniu sighed, "So, Xiu Xiu, you have to help me keep this secret, we can't let my sister-in-law know that I've regained my senses for now."
"Don't worry, since Xiu Xiu has promised you, she will definitely keep your secret," Xu Xiuxiu said with a playful laugh.
She had been worried that Chen Erniu and He Hongjuan had done something irreversible.
