At least Chen Chuyu appreciates Su Xuan more. Being with Su Xuan means being a wife, not the third wheel like with Du Haitao. Those are completely different.
Of course, Chen Chuyu is also a visual creature. Comparing Du Haitao to Su Xuan, Su Xuan's looks would probably leave him hundreds of streets behind. So, choosing someone, he couldn't possibly choose Du Haitao. More importantly, Du Haitao was exceedingly hypocritical, a person so fake it's unbearable.
So, after much mental struggle, Chen Chuyu has already decided to marry Su Xuan. He has no family and doesn't need to say anything about it to anyone.
"I think he would."
Su Xuan said meekly, thinking to himself that his children usually call all the wives 'mom,' so to him, they should call Chen Chuyu mom too. Su Xuan naturally noticed that Chen Chuyu had decided to be with him, feeling rather awkward. However, it seems like another person would join his harem, something he realizes he cannot stop.
