Jin Hengyuan was in a bad mood when he walked out of the restaurant.
If he had been more selfish, he could have taken the case first without caring about anything else. He could have taken the opportunity to thoroughly understand the cause and effect of Su Mubai's marriage and divorce. Only by knowing his enemy and himself could he have prevented it from happening. However, that method was too despicable. Once Su Jin found out about this, he would be branded as despicable and shameless.
This was one of the reasons why he didn't answer.
Secondly, his intuition was telling him that Su Mubai had no choice but to marry another woman, and that he was still deeply in love with her. The more he understood, the more his conscience would torment him.
After all, Su Mubai's deep love was now his wife. He couldn't let his woman help him achieve his dreams after personally freeing him from the shackles of marriage.
He was not that great.
