The situation now is that if anything ever happened to the Guan Family in the future, the one begging for help wouldn't be Qin Yucen, but him.
Maybe this is the inferiority of men, they secretly wish their women to live miserably without them, so they can appear as saviors and behave as though they are superior. Only then can they satisfy their own vanity.
But when exactly did Huo Jingtang and Qin Yucen start their affair, before the divorce or after? Was it when she went to Tanghuang to discuss a contract, or that time at the police station, or today... How could he be so blind not to see that they only had eyes for each other? He should have realized, back at the police station, that Huo Jingtang speaking up for Qin Yucen was odd, for a man who never cared about women to defend one who was of no relation to him. It was all because Zhong Lang had confused him, made him unable to see clearly, and had him believing all along that Qin Yucen was entangled with him.
